Allen tweeted a retirement announcement Thursday morning.

EDGE Analysis

Even with his obvious decline the past two seasons, the 33-year-old Allen finishes his career tied with Julius Peppers for ninth place on the all-time sacks list at 136.0, which should at least give him a fringe case for the Hall of Fame. As a bonus, Allen may have topped Marshawn Lynch for 2016's most entertaining retirement announcement.

EDGE Analysis

One of the Panthers' inactives in the NFC championship game, Allen will return to a starting gig, which equated to 63 percent of the defensive snaps in 12 regular season appearances upon arriving in Carolina after Week 3. However, he put up just two sacks over the course of the year.

Allen (foot) is listed as probable for Sunday's Super Bowl versus the Broncos, James Palmer of NFL Network reports.

EDGE Analysis

Allen has endured an interesting past few weeks, which included a DNP in the NFC championship game, no presence on last week's injury report, and a reappearance this week with a limited showing Wednesday. However, he practiced in a full capacity both Thursday and Friday, and head coach Ron Rivera even expects Allen to start Sunday, according to the Charlotte Observer. In 13 games with the Panthers this season (including playoffs), Allen accumulated two sacks among 27 tackles.

Allen (foot) was a full practice participant Thursday, Max Henson of the Panthers' official site reports.

EDGE Analysis

Allen sidestepped the first injury report in advance of the Super Bowl, yet he landed on this week's version due to his healing foot, which forced a limited showing Wednesday. However, his return in a full capacity Thursday implies that he's in line to play Sunday against the Broncos. If he suits up, he'll be seeking his second career sack of Peyton Manning.

Allen (foot) was a limited practice participant Wednesday, Jonathan Jones of the Charlotte Observer reports.

EDGE Analysis

After missing the NFC championship game due to a fractured foot, Allen avoided the injury report last week, only to make a return on the first version this week. The development follows a media session at Monday's Opening Night in which he told NFL Network that he feels "great. Honestly, I feel, hopefully, I'll be a tremendous factor in this game. So, as far as physically, 100 percent ready to go, just preparing like normal." With a limited showing under his belt, he may just be easing into Super Bowl week prep, but the pass rusher's availability will be worth watching in advance of the contest.

Allen wasn't listed on the Panthers' injury report Wednesday, Jonathan Jones of the Chrlotte Observer reports.

EDGE Analysis

After sustaining a fractured foot in the divisional round against the Seahawks, Allen was shelved in the NFC championship game in order to avoid a setback. Avoiding the initial Super Bowl injury report entirely sheds light on the extent of the injury and paves the way for active status in the big game. In 12 regular season outings with the Panthers, he totaled two sacks among 27 tackles (15 solo).

Allen (foot) has been ruled out for Sunday's NFC championship game against Arizona.

EDGE Analysis

As a result, Kony Ealy will draw a start at DE for the Panthers on Sunday in place of Allen, with rookie Ryan Delaire also slated to be active for the contest. Meanwhile, coach Ron Rivera relayed Friday that Allen -- who logged 32 tackles and two sacks in 12 games this past season -- would have a chance to play in the Super Bowl, in the event that the Panthers are able to get past the Cardinals this Sunday.

Allen (foot) was limited in practice on Thursday.

EDGE Analysis

Head coach Ron Rivera said that Allen has a shot of being listed as questionable for Sunday's NFC Championship matchup with the Cardinals. If Allen can't go, Rivera confirmed that Kony Ealy would take over the starting role at defensive end, with Ryan Delaire serving as backup. An official decision should come sometime on Friday after the Panthers finish their practice.

Allen has been diagnosed with a fractured foot and will be listed as doubtful for Sunday's NFC championship game against the Cardinals, Joe Person of the Charlotte Observer reports.

EDGE Analysis

Allen sustained the injury during Sunday's divisional-round victory versus the Seahawks, and subsequent examinations confirmed its extent. While the Panthers will take the healing process day by day, head coach Ron Rivera is unsure whether or not Allen will require surgery. However, Wes Horton is the prime candidate to be promoted from the practice squad, if Allen is unable to recover in time for Sunday's contest.

Allen suffered a fractured foot during Sunday's playoff win over the Seahawks, ESPN.com reports.

EDGE Analysis

Allen's injury was initially diagnosed during Sunday's game, but he's reportedly scheduled for a more thorough doctor's evaluation Monday morning. At that point, a more definitive diagnosis could surface, which would clarify if he'll be available in any capacity going forward in the playoffs. Regardless of whether Allen is ultimately ruled out, expect Kony Ealy and Mario Addison to see more snaps opposite Charles Johnson at defensive end.
