Arizona starting OT Keith out for the season

Posted: Updated:

TEMPE, Ariz. (AP) -- The Arizona Cardinals' starting offensive right tackle, Brandon Keith, is out for the remainder of the season because of hamstring and knee injuries.

Keith apparently hurt his hamstring early in Sunday's 36-18 loss to Seattle but returned to finish the game. Keith moved into the starting job this season when Levi Brown was moved to left tackle.

He wasn't mentioned among the injured at coach Ken Whisenhunt's Monday news conference but, according to, an MRI surprisingly showed a torn hamstring.

Keith, placed on injured reserve on Tuesday, also will undergo arthroscopic knee surgery.

Jeremy Bridges is the probable replacement but the Cardinals added depth at the position by signing tackle D'Anthony Batiste, who played in five games for Denver before being released on Oct. 16.
