What happened: The Arizona Cardinals have signed defensive lineman Kaleb Proctor. The move adds a body to the team's defensive line group as the roster takes shape ahead of the 2026 season.

Why it matters: Defensive line depth is a recurring offseason priority, and signings like this round out the rotation and training-camp competition. Roster spots along the front are won in camp, and added bodies give the coaching staff more options to evaluate before the season opener.

What to watch: Watch how Proctor factors into the defensive line rotation through training camp and the preseason as Arizona finalizes its 53-man roster.
