Tretter announced his retirement from the NFL on Thursday, Daniel Oyefusi of the Miami Herald reports.

EDGE Analysis

Tretter will hang up his cleats after an eight-year career with the Packers and Browns. The center will finish with 90 starts under his belt and will now shift his focus solely to being the NFLPA president, a role he's been in since 2020.

Cleveland will release Tretter on Tuesday, Adam Schefter of ESPN reports.

EDGE Analysis

Tretter's release will clear $8.2 million in cap space for the Browns to maneuver in free agency, but losing one of the more reliable centers in the league is also a notable blow for a run-first offense. The transaction appears to set up 2020 fifth-round pick Nick Harris to start at center for the 2022 season. Tretter, whose only missed game in the last five years came as a result of COVID-19 protocols, will enter his age-31 season in a new uniform.

Tretter (knee/illness) was activated from the reserve/COVID-19 list Thursday.

EDGE Analysis

Tretter tested positive for the virus last week but is now clear of the health and safety protocols. The 30-year-old was a limited participant at Thursday's practice due to a knee injury.

Tretter (illness) was placed on the reserve/COVID-19 list Thursday, Nate Ulrich of the Akron Beacon Journal reports.

EDGE Analysis

Tretter announced via his personal Twitter feed that he has tested positive for the virus but is vaccinated, so he'll have a chance to play Saturday. If he's sidelined in Week 16, Nick Harris will likely draw the start at center as the Browns face off with the Packers on Saturday.

Tretter (knee) is active for Sunday's game against the Chargers.

EDGE Analysis

Tretter continued the same trend of the last few weeks, recording just one limited practice but still suiting up Sundays. The presence of the starting center means Michael Dunn and Hjalte Froholdt will likely assume backup roles.

Tretter (knee) is listed as questionable for Sunday's game against the Chargers.

EDGE Analysis

Tretter managed to record one limited practice session yet again this week. While this may seem like a negative, the center has suited up for his team's last two games after recording only one limited practice in the weeks leading up to those games. Expect Michael Dunn or Hjalte Froholdt to fill in for Tretter if he can't play Sunday.

Tretter (knee) is active Week 4 against Minnesota, Mary Kay Cabot of The Cleveland Plain Dealer reports.

EDGE Analysis

Tretter was once again only able to log one limited practice session this week, but as has been the case for the last two weeks, it won't prevent him from suiting up. This has the appearance of an issue the veteran offensive lineman will be managing throughout the early part of the season.

Tretter (knee) is active Week 3 against Chicago, Mary Kay Cabot of The Cleveland Plain Dealer reports.

EDGE Analysis

Both Tretter and offensive tackle Jedrick Wills managed injuries this week during practice, but this was a similar situation as last week and both ended up playing. That will be the case again Sunday, and it's possible this could be the norm with respect to practice time moving forward.

Tretter (knee) is active Week 2 against the Texans, Mary Kay Cabot of The Cleveland Plain Dealer reports.

EDGE Analysis

Tretter missed back-to-back days of practice this week before logging a limited session on Friday, but will suit up anyway despite a "questionable" tag. He was considered questionable for last week's tilt as well, but the veteran center ended up logging 59 snaps. It seems like injury maintenance may be part of his weekly routine moving forward.

The Browns listed Tretter (knee) as questionable ahead of Sunday's contest with the Texans, Mary Kay Cabot of The Cleveland Plain Dealer reports.

EDGE Analysis

Tretter was listed as questionable ahead of Week 1, but he still played 59 snaps. The 30-year-old will likely be a game-time decision Sunday.
