Rucker suffered a sprained MCL and is expected to miss around two-to-three weeks, Darren Urban of AZcardinals.com reports.

EDGE Analysis

Rucker had offseason ankle surgery and dealt with some other minor injuries in the lead-up to the team's regular season opener on Sunday. However, he was cleared prior to the game and resumed his role as a starter at defensive end. The injury bug has struck again for Rucker, who has now suffered a sprained MCL. He's expected to sit out around two-to-three weeks, so look for Rodney Gunter or Robert Nkemdiche to see some increased reps in his place.
