The Cardinals opened the 21-day practice window for defensive tackle Bilal Nichols to return from the physically unable to perform list, per team writer Zach Gershman.

Since Arizona played on Thursday night in Week 4, they started their practice week on Monday with Nichols in the mix. The eight-year veteran started the 2025 season on the physically unable to perform list after sustaining multiple stingers in 2024 that turned into a season-ending neck injury. He will have three weeks to practice before he must be added to the active roster or revert to the PUP list for the rest of the season.

Nichols’ return would be a major boost to a Cardinals defensive line that has been decimated by injuries. Veterans Justin Jones and L.J. Collier are already out for the year, while first-round rookie Walter Nolen landed on the PUP list before training camp even began. Second-year defensive tackle Darius Robinson also left last week’s game with a chest injury and did not practice on Monday.

The injuries have forced the Cardinals to rely heavily on third-year UDFA Dante Stills alongside veteran starters Calais Campbell and Dalvin Tomlinson. Campbell and Tomlinson have largely held up, but Stills’ 47.2 grade from Pro Football Focus (subscription required) is the seventh lowest among defensive linemen with at least 115 snaps. (Robinson’s 35.5 grade is the second-lowest in the same group.) As such, Nichols’ return would significantly help reinforce the unit.

“[Nichols] can play a couple of different hats for us,” said head coach Jonathan Gannon after Monday’s practice. “Good to have him back out there today. He plays the way we want him to play. He’s got energy and juice, so it was good to see him out there.”

Opening Nichols’ window as soon as he became eligible is a good sign for his return timeline, but neck injuries are notoriously tricky and the Cardinals are unlikely to rush him back to the field.
