Collins announced his retirement from the NFL on Friday, Daniel Chavkin of SI.com reports.

EDGE Analysis

"It hasn't hit me yet, but I'm officially retired," Collins said in announcing his retirement. The 33-year-old played 10 seasons in the league, tallying a career-best 115 tackles in 2014 for the Patriots and peaking with seven sacks in 2019 in his return to New England. Collins also made one All-Pro team and one Pro Bowl, both in 2015. He spent most of last year on the Patriots' practice squad.

Collins reverted back to the Patriots' practice squad Tuesday.

EDGE Analysis

Collins was elevated to New England's active roster prior to Monday night's matchup against the Bears, where he eventually failed to record any stats despite logging 22 defensive snaps and five special teams reps in the contest. The 33-year-old has suited up for a combined 13 games over the past three NFL seasons, and he'll now return to the team's practice squad as an emergency depth option.

Collins signed with the Patriots' practice squad Monday, Evan Lazar of the team's official site reports.

EDGE Analysis

It was previously unclear what type of contract Collins inked with New England, though he's now set to join the team's practice squad after fellow linebacker Harvey Langi was released Monday. The 32-year-old has yet to play in 2022, though his experience from four previous stints with the Patriots should make him a prime candidate for game-day elevations moving forward this season.

Collins was signed by the Patriots on Monday, Andrew Callahan of the Boston Herald reports.

EDGE Analysis

It's unclear whether Collins will report to the practice or the active roster, but the linebacker is returning for a fourth stint with the Patriots. Collins appeared in 10 games with New England last year, registering 20 tackles, including a sack, while also intercepting a pass and deflecting three others.

Collins (ankle) is listed as active Saturday in Buffalo.

EDGE Analysis

Collins made a surprise appearance on Wednesday's injury report and capped the week of prep with a limited practice Thursday, entering the weekend as questionable to play in the wild-card round. It may have been a case of maintenance to give the ninth-year pro a midweek respite, but he'll be available to the Patriots' group of linebackers Saturday.

Collins (ankle) was a limited participant at Thursday's practice.

EDGE Analysis

The linebacker popped up on the Patriots' injury report Wednesday with an ankle issue, but he was able to practice in a limited capacity Thursday. Collins will now enter the Patriots' wild-card game against the Bills with a questionable designation and if he can't play, Josh Uche would likely step into a larger role.

Collins was activated from injured reserve by the Patriots on Monday, Mike Reiss of ESPN.com reports.

EDGE Analysis

Collins should slot in at his usual backup outside linebacker role in Monday night's matchup against Buffalo. This will be the veteran's first game since going on injured reserve three weeks ago.

Collins (ankle) was spotted practicing Wednesday, Zack Cox of NESN.com reports.

EDGE Analysis

With the linebacker returning to practice for the first time since going on IR prior to the team's Week 10 matchup, the Patriots have a 21-day window to restore him to their active roster. Otherwise, he will be forced to miss the remainder of the season. Collins has played a minor role in his five games since joining the Patriots, recording seven tackles, a sack and an interception.

Collins (ankle) was placed on injured reserve Saturday.

EDGE Analysis

Collins was initially listed as doubtful for Sunday's game against the Browns, but he'll now be forced to miss at least three contests. Josh Uche and Ronnie Perkins should see additional playing time in his absence.

Collins (ankle) is listed as doubtful ahead of Sunday's game against the Browns.

EDGE Analysis

Collins picked up an ankle injury in the Pats' Week 9 victory over the Panthers. Should he end up not being able to suit up against Cleveland -- he appears to be trending in that direction -- some combination of Josh Uche and Ronnie Perkins would be in line for extended roles.
