Collier (knee) was activated off the injured reserve list Wednesday, Darren Urban of the Cardinals' official site reports.
EDGE Analysis
The 30-year-old practiced in full throughout last week and is now in line to return following a 13-game absence due to a knee injury. Through 17 appearances in 2024, Collier recorded 29 total tackles, including 3.5 sacks, and two passes defensed. Now fully healthy, he's expected to operate as one of Arizona's top interior defensive linemen in the Week 17 matchup against the Bengals.

Collier (knee) was not activated off injured reserve Saturday.
EDGE Analysis
Collier's practice window was opened Dec. 3, so if the Cardinals do not activate the defensive tackle before Dec. 24, he will need to remain on injured reserve for the remainder of the 2025 season. The 30-year-old has played just 34 defensive snaps through two games this season, accumulating one solo tackle in the playing time.

Collier (knee) was designated to return from the injured reserve list Wednesday, Darren Urban of the Cardinals' official site reports.
EDGE Analysis
The 30-year-old has missed the Cardinals' last 10 games after sustaining a knee injury in the Week 2 win over the Panthers, but it now appears he's nearing a return. Collier was one of Arizona's best interior defensive linemen in 2024, recording 29 total tackles, including 3.5 sacks, and two passes defensed across 17 contests. Once fully healthy, he's expected to add depth to the Cardinals' defensive line.

Collier (knee) was placed on injured reserve Wednesday.
EDGE Analysis
Collier sustained a knee injury in Arizona's Week 2 win over the Panthers, and the issue now appears serious enough to sideline him for at least the next four games. The 2019 first-round pick from TCU appeared in 17 games for the Cardinals last season, recording 29 total tackles, including 3.5 sacks, and two passes defended. In his absence, PJ Mustipher is likely to see increased work as a rotational interior defensive lineman.

Collier (knee) has been ruled out for the remainder of Arizona's matchup versus the Panthers on Sunday, Theo Mackie of The Arizona Republic reports.
EDGE Analysis
Collier picked up the injury in the first quarter of the game, and it's severity is currently unknown. PJ Mustipher will likely see increased playing time at defensive tackle in Collier's absence.

Collier is questionable to return to Sunday's game against Carolina due to a knee injury, Theo Mackie of The Arizona Republic reports.
EDGE Analysis
Collier likely picked up the injury during the first quarter of Sunday's game, and he'll undergo more testing to determine the severity of the issue. PJ Mustipher is in line to see an uptick in snaps at defensive tackle for as long as Collier is sidelined.

Collier signed a one-year, $4 million contract with the Cardinals on Wednesday, Josh Weinfuss of ESPN.com reports.
EDGE Analysis
Collier appeared in all 17 regular-season games for the Cardinals in 2024 -- which was the first time he's done that in his six-year NFL career -- and he finished with career highs in total tackles (29) and sacks (3.5). Collier will remain in Arizona for the 2025 campaign and likely serve in a rotational role at defensive end behind Justin Jones (triceps) and Josh Sweat.

Collier finished the 2024 season with 29 total tackles (13 solo), including 3.5 sacks, while also adding two passes defensed and a fumble recovery over 17 games.
EDGE Analysis
Collier had a career year in 2024, setting new career highs in tackles and sacks, while appearing in all 17 games for the first time in his six years in the NFL. The defensive end will enter the offseason as an unrestricted free agent and his 2024 performance will certainly draw the attention of plenty potential suitors.
