Cooley has struggled so far this year after enjoying a career year in 2010. He has just six catches and 66 yards in four games this season. Video of the play in which Cooley was injured is embedded below -- it didn't look serious, so it's possible he may be able to return. Cooley has been dinged up quite often this year -- earlier this week, he had his surgically-repaired knee drained, although he downplayed the procedure to reporters.
Update: Cooley suffered a broken left index finger, according to Grant Paulsen on Twitter.
