SAN DIEGO -- Chargers coach Norv Turner said Monday that inside linebacker Stephen Cooper suffered a torn biceps muscle in Sunday night's 20-7 preseason victory over the Dallas Cowboys. The San Diego Union-Tribune reported that Cooper will have surgery and will be placed on injured reserve, meaning the nine-year veteran likely will be lost for the season.
Turner told the newspaper that Floyd was "doing extremely well. He cleared up."
Turner added that the team would "be careful" with Floyd this week.
Wide receiver Patrick Crayton has bone spurs in an ankle and will have arthroscopic surgery, according to Turner. He's expected to be out 10 days to two weeks.
Floyd, a seven-year veteran, totaled 37 catches for 717 yards and six touchdowns last season.
