Arizona Cardinals outside linebacker Alex Okafor will miss the remainder of the regular season with a torn biceps, reports FoxSports.com.
Cardinals head coach Bruce Arians made the announcement on his weekly radio show on Tuesday.
Okafor was the team's fourth-round pick in April's draft.
According to the team's website, Okafor was set to start this Sunday's game against the Tampa Bay Buccaneers. Okafor has one tackle in limited action this season.
The team signed Vic So'oto on Tuesday and promoted Dontay Moch from the practice squad to add some depth at linebacker.
The team had only two outside linebackers left on the active roster before those roster moves.
