Linder announced his retirement from the NFL on Monday, Michael DiRocco of ESPN.com reports.

EDGE Analysis

Linder hangs up the cleats after eight NFL seasons, all of which were spent with the Jaguars. The starting center's retirement frees up $10 million in salary cap space for Jacksonville but leaves the team with another notable hole to fill on the O-line as April's draft approaches.

Linder (illness) was activated from the reserve/COVID-19 list Tuesday, Aaron Wilson of Sportstalk 790 Houston reports.

EDGE Analysis

Linder was sidelined for the final two games of the season while in the COVID-19 protocols. The 29-year-old played exactly nine games for the third time in the past four seasons as he continues to deal with injuries. Linder remains under contract for 2022, but he could be cut with no dead cap hit, so Jacksonville could opt to move on this offseason.

Linder (illness) was placed on the reserve/COVID-19 list Monday after he tested positive for the virus, Tom Pelissero of NFL Network reports.

EDGE Analysis

Linder has had a rough season dealing with knee and back injuries and now lands on the COVID list. If he is unable to clear protocols in time for Sunday against the Patriots, Tyler Shatley would likely start.

Linder (back) was a full practice participant Friday.

EDGE Analysis

Linder suffered the injury in Week 13 and was inactive for Sunday's 20-0 loss to the Titans. However, it appears as if his absence will be limited to one full game, and he is in line to suit up Sunday against Houston. Linder should return to his role as Jacksonville's starting center.

Linder (back) is out for Sunday's matchup against the Titans, Jim Wyatt of the Titans' official site reports.

EDGE Analysis

Linder suffered the back injury in Jacksonville's Week 13 matchup against the Rams, and he failed to practice in any capacity all week. As a result, he'll sit for Sunday's Week 14 matchup against Tennessee, with Tyler Shatley likely to take over starting duties at center.

Linder suffered a back injury in the Jaguars' 37-7 loss to the Rams on Sunday, John Oehser of the Jaguars' official site reports.

EDGE Analysis

Linder was announced as questionable to return, but he never did. The severity of the injury is unknown, but he'll try to return in Week 14 against the Titans. If he is unable to go, Tyler Shatley will likely continue to fill in as the starting center.

The Jaguars activated Linder (knee) from injured reserve Saturday, Michael DiRocco of ESPN.com reports.

EDGE Analysis

Linder will be active Sunday for the first time since suffering an MCL sprain in Week 4. The veteran center is expected to reclaim his starting spot along the offensive line.

The Jaguars designated Linder (knee) for return from injured reserve Wednesday.

EDGE Analysis

The transaction kicks off a 21-day window wherein Linder can be evaluated at practice. He'll be eligible to rejoin the active roster at any point in that span, making Sunday's game against the 49ers the first possible opportunity for Linder to return the field. Linder, who opened the season as the Jaguars' starting center, hasn't played since early October due to an MCL sprain.

Linder was placed on the injured reserve list on Tuesday due to an MCL sprain, Aaron Wilson of Sportstalk 790 Houston reports.

EDGE Analysis

Linder was injured in Sunday's game. It was previously reported he would likely miss 4-to-5 weeks, so this news comes as no surprise. It's likely that Tyler Shatley will step into Linder's starting offensive line role moving forward.

Linder is expected to miss 4-5 weeks with a high ankle and MCL sprain, Mark Long of the Associated Press reports.

EDGE Analysis

Linder had played every snap this season before leaving early Sunday. The former 2014 third-round selection has been a mainstay on the Jaguars offensive line. Tyler Shatley, another eight-year veteran, will likely step into the starting center role Week 6 against the Dolphins.
