The Arizona Cardinals placed defensive tackle PJ Mustipher on injured reserve on Saturday because of a foot injury, meaning he will miss the entire 2026 season.
The Cardinals also placed defensive back Jaden Davis on IR due to an undisclosed injury sustained during the team’s second padded practice of training camp.
In corresponding moves, Arizona signed defensive lineman Brodric Martin, 27, and safety Quinton Newsome, 25.
Mustipher, 26, made 32 tackles in 15 games as a reserve last season with the Cardinals. The nose tackle played on 30% of the defensive snaps (300) and 20% on special teams (78).
He was on the Arizona practice squad for the 2024 campaign. He also played in four games for the New Orleans Saints in 2023, making four tackles.
Davis, 25, was a seventh-round pick by the Cardinals in the 2024 NFL Draft.
