Stephen Cooper out 2-3 months

SAN DIEGO -- Chargers coach Norv Turner says inside linebacker Stephen Cooper will have surgery on a torn biceps muscle and be out for two to three months.

Cooper was hurt in an exhibition victory at Dallas on Sunday night.

Turner also says wide receiver Patrick Crayton has bone spurs in an ankle and will have arthroscopic surgery. He's expected to be out 10 days to two weeks.

Turner says wide receiver Malcom Floyd is fine after being knocked out of the game with a concussion.

The Chargers play at Arizona on Saturday.
