Lions training camp medical preview: Offensive line
There aren't many health concerns for this group entering the season. The main issue may finding quality backups for Graham Glasgow and Taylor Decker who are advancing in age. The other big question is who will be replacing the retired Frank Ragnow at center.
The continued strong performance of the offensive line will be a huge key for the 2025 season. The Lions team identity has centered around an elite running game since Dan Campbell took over. This preseason will be fascinating as there are many young, unproven players who will battle it out for important starting and backup roles on the team.
Ten offensive linemen made the initial 53-man roster last season (Decker, Glasgow, Ragnow, Kevin Zeitler, Penei Sewell, Colby Sorsdal, Kayode Awosika, Gio Manu, Dan Skipper, Michael Niese).
Here is the list of offensive linemen starting with the players with the biggest medical question marks entering the season. Ages are at the start of the season.
#1: Graham Glasgow - 33yo
Glasgow is the biggest offensive line health concern heading into the season. A reliable, solid player for most of his career, his performance dipped last season possibly due to knee injuries. He was listed twice with an unspecified knee last season and missed one game due to it. There was no specific injury seen on video last year.
The offseason news is good so far as he was a full participant at OTA last month.
Projection: Glasgow starts at the RG position in Week 1. Hopefully last season was an aberration and we see a return to form.
#2: Taylor Decker - 32yo
Decker suffered multiple minor injuries last season including a right pec strain, a rotator cuff (1 game missed), and a right MCL/ankle (2 games missed). None of those issues are of significant concern heading into the season. He was a full participant at OTA which is a great sign.
The prior offseason, he had a toe sesamoidectomy which is something to monitor for the rest of his career. As seen with Ragnow, a big toe issue can have career-ending ramifications.
Decker was surprisingly placed on PUP at the start of camp but the fact that he was a full participant at June OTA is reassuring. Good chance his PUP stint is brief.
Projection: Decker enters the season in good health and continues to lock down the LT position as he has the past nine seasons.
#3: Tate Ratledge - 24yo
His slightly-older rookie age means he needs to contribute as soon as possible. We saw that already in OTA where he was starting at the center position in place of Ragnow.
Off-the-field, Ratledge also appears to be a Ragnow reincarnate.
Medically, there are some significant surgeries in his past. He enters his rookie season healthy though.
The main concern was that he was part of the 2nd-round rookie class that remained predominantly unsigned. A couple teams at the top of the second round (Browns & Texans) broke rank by giving out fully-guaranteed contracts which caused problems for all the other teams.
Fortunately, dominos began to fall around him, and Ratledge agreed to terms on July 17.
Projection: With Ratledge signed, sealed, and delivered in time for the start of camp, he's a day 1 starter at center. While there may be some growing pains, he is expected to lock down the position for many years.
#4: Christian Mahogany - 24yo
Mahogany performed well in limited action last season. The mononucleosis that knocked him out of last year's training camp and the early part of the season is of no concern. Of more importance, he has a history of a right ACL tear in 2022 and was wearing a right knee brace all last season.
He was a full participant starter at OTA at the LG position and enters camp healthy.
Projection: Mahogany is the starter at LG in Week 1.
#5: Dan Skipper - 30yo
Skipper played through a painful, suspected rib injury last season. Despite the injury, he was available in every game and enters the season healthy. His age means that the Lions are actively trying to develop a replacement.
Projection: Skipper performed well as the jumbo TE and primary OT backup last season and starts the season again in that role.
#6: Netane Muti - 26yo
Muti has a significant medical history with a pec rupture, Lisfranc, and Achilles rupture. He missed all last season due to the pec. He's still young which hopefully helps him going forward. He was a full participant at OTA which is a good sign.
Projection: Muti's riddled injury history makes it an uphill battle for him to find a spot on the team.
#7: Jamarco Jones - 29yo
Jones has a history of a high ankle sprain and shoulder in his past. He played four offensive snaps with the Lions last season and enters the season healthy.
Projection: Jones will compete for a backup OT position.
#8: Kayode Awosika - 26yo
Awosika has been a valuable reserve OG for the Lions the past three seasons. Last year, he played 147 offensive snaps. He enters the season healthy.
Projection: His solid performance in previous years gives Awosika an edge in winning a backup job.
#9: Giovanni Manu - 24yo
The Lions traded up to grab Manu in the 2024 4th-round in the hopes he will develop into a quality OT. He didn't see the field as a rookie last season, and it's time to show progress as he enters his second year.
Projection: Preseason will be big for Manu as he tries to overtake Skipper for the primary backup OT job. Even if he doesn't win that job, he still makes the 53-man roster. His young age and potential gives him an edge over his competition.
#10: Kingsley Eguakun - 24yo
Eguakun had his final college season in 2023 shortened due to an ankle injury, but that shouldn't be a major concern now.
He joined the Lions as an undrafted rookie last year but didn't see any action. Early signs this offseason suggest he is in strong contention for a backup position. Jeff Risdon recently observed that Eguakun was the primary center backup at OTA.
Projection: His young age gets him a role at least on the practice squad.
#11: Colby Sorsdal - 25yo
Sorsdal didn't see an offensive snap last season. He enters his 3rd year hoping to earn a backup position. Jeff Risdon observed during OTA that Sorsdal was taking some snaps at center which makes you wonder if it's a last-ditch effort to find him a role on the team. He was a full participant at OTA and enters camp healthy.
Projection: This preseason is crucial for Sorsdal as time may be running out for him. The position he plays during preseason will be interesting to see.
#12: Miles Frazier - 23yo
There were no medical concerns coming out of college for this 5th-round rookie. He was not a full participant at OTA, but there was no indication of a significant issue. Surprisingly, he was placed on PUP at the start of training camp for unknown reasons.
Positional versatility increases his value as he played OG and OT in college.
Projection: Let's assume the PUP stint is short. Frazier makes the 53-man roster as a backup who may end up playing key snaps if there are any injuries. Given his youth and health, it would be ideal for the team if earns the primary OG backup role in similar fashion to Mahogany last year.
#13: Michael Niese - 27yo
Niese played 35 snaps last season as a backup. He was a full participant at OTA and enters the season healthy.
Projection: Niese was an important backup center last season. We'll see if he can hold onto that role in spite of younger competitors like Eguakun.
#14: Trystan Colon - 27yo
Colon played all 17 games last year with the Cardinals. He was signed after Ragnow retired.
Projection: He's got a decent amount of playing experience in the NFL over the past two seasons which could be valuable.
#15: Penei Sewell - 24yo
There are no health concerns for this perennial All-Pro. He had multiple minor ankle sprains last season as well as an ugly left knee hyperflexion in the playoffs, but did not miss a single game. He was a full participant in June OTA.
Projection: This 4th-year player is still implausibly young. Entering the season, Sewell is favored to win the NFL's new Protector-of-the-Year award which goes to the best offensive lineman.

Shedeur Sanders Has Officially Been Called Out By The Browns
Shedeur Sanders Has Officially Been Called Out By The Browns originally appeared on The Spun. Shedeur Sanders has officially been called out by the Cleveland Browns for his off-the-field behavior. The fifth round NFL Draft pick is no lock to make the team. Sanders, one of two quarterbacks drafted by the Browns - Oregon's Dillon Gabriel being the other - has had a couple of off-the-field incidents so far. He has reportedly twice been pulled over for speeding, once going around 100 MPH. Cleveland Browns general manager Andrew Berry officially called out the young quarterback while speaking to the media at training camp earlier in the week. The Browns admitted that what Sanders has been doing is "not smart." Berry didn't hold back when discussing Sanders' off-the-field incidents. "Not smart. Just not smart," Berry said. "It's something that we've addressed with him. Look, he understands the implications, he understands the consequences. It's not just about yourself. It's not just about having a joyride, but that you could injure other people. … A deer or something cuts in front of you, your reaction time, it's just dangerous." Sanders, meanwhile, has said that he's learned his lesson. He won't be driving fast anymore. "Yeah, I definitely learned not to drive fast at all," Sanders told reporters. "So I really don't even drive that much anymore. But I really don't drive fast at all. So I definitely follow the rules and I hope everybody learned from my situation, you know that not drive fast at all." Sanders was first cited on June 5 for driving 91 MPH in a 65 MPH zone. Less than two weeks later, he was cited for driving 101 MPH in a 60 MPH zone. The rookie NFL quarterback settled both tickets, paying more than $500 in fines and court fees. Sanders promises that he's learned his lesson from the two speeding incidents. Shedeur Sanders Has Officially Been Called Out By The Browns first appeared on The Spun on Jul 27, 2025 This story was originally reported by The Spun on Jul 27, 2025, where it first appeared.

Texans DB Jalen Pitre, LB Christian Harris miss consecutive training camp practices
Two more name to watch for this upcoming week Two starters for the Houston Texans' defense missed practice back-to-back days, but for one player, it's not much of a concern. For the other? Time could be pressing if he plans on securing a starting job for the upcoming season amid a contract year. Nickel defender Jalen Pitre and linebacker Christian Harris missed Saturday's practice, though both were in attendance among the fans and greeted folks after drills. For Pitre, Saturday marked the second consecutive practice missed with an undisclosed injury. For Harris, he's yet to see action in any practice because of a lower-body injury that hindered his playing time last year. Despite being cleared from starting the season on the PUP list, Harris hasn't taken snaps during teams drills. Texans coach DeMeco Ryans said that Pitre, like all players, would be on their "own timeline" regarding a return. For Pitre, he's not expected to miss much time and could be back at practice by Monday morning. Pitre, who inked a three-year, $42 million extension this offseason, was having a career year after moving to the nickel from safety in 2024 before a chest injury cut his season short. In the early stages of training camp, he's impressed in coverage, picking off C.J. Stroud on the second day of practice for a return for a touchdown. "He's been a guy who's been very consistent for us, no matter where we've put him or what we've asked him to do. He's just my type of player," Ryans said. "He's all over the field, always up for the challenge. Whatever the down is, he's going to be around the football and making plays and it was evident today.' Harris, who enters the final year of his rookie deal, hopes to return to his 2023 form. When Ryans arrived from San Francisco, no one benefitted more than Harris, who notched 101 tackles, two sacks, three forced fumbles and a pick-six in the wild-card round victory over the Cleveland Browns. With both Henry To'oTo'o and E.J. Speed seeing extended time in the starting lineup, every practice missed for Harris could inch closer to him finding a new home in 2026. The Texans return to practice on Monday.

Former Pro Bowl safety Jamal Adams is switching positions with Raiders
Safety seems like it's been a busy position for the Raiders this offseason. They gave Isaiah Pola-Mao a long term extension and their only free agent addition to sign more than a one-year deal was safety Jaremy Chinn, seemingly giving them two new starters to replace the losses of Tre'von Moehrig and Marcus Epps. Then the same day they added Chinn, they also signed Lonnie Johnson Jr. So, they seemed set. And yet just prior to the first day of camp they also added safety TJ Scott and former Pro Bowl safety Jamal Adams. Now, suddenly they were looking at a logjam at safety. But when Adams took the field, he was working with the linebackers instead. The 6-1, 213-pounder is trying to make a comeback after splitting last season between the Titans and the Lions' practice squad. And his former Seahawks head coach sees a change of positions is the best way to accomplish that. "I told him right off the bat, I want him to play inside," Carroll said of Adams. "He's always been so instinctive and so aggressive and such a run-through guy, been a fantastic blitzer over his time. So, I want to put him in position to do that. So, he's jumped right into the WILL spot, and that gives us some flexibility that we're going to grow with. He looks really good. He had a real serious injury a bit ago. He looks like he's back. Weighing a little bit more than he was before, he fit just right. I'm really anxious to see how he takes it." Linebacker has also been completely overhauled this offseason for the Raiders. Former starters Robert Spillane and Divine Deablo were allowed to leave in free agency. They then seemingly replaced them with former Steelers MLB Elandon Roberts and former Bucs OLB Devin White. Now both Roberts and White have some competition with the additions of Adams and former Bengals LB Germaine Pratt. Carroll has preached competition. He wasn't lying.
