Adams suffers injury
Rookie defensive end Gaines Adams missed practice today with a chest injury that coach Jon Gruden said was suffered in practice, probably on Wednesday.
It's not clear how serious the injury is and Gruden wouldn't speculate on whether Adams will play at Detroit on Sunday.
Also, tight end Alex Smith (ankle), defensive end Patrick Chukwurah (shoulder) and Brian Kelly (groin) missed practice. They're availability for Sunday hasn't yet been determined, but it doesn't look good for any of them. Smith said today he did not damage any ligaments in his ankle, so that's positive. He also said the injury is not believed to be a high ankle sprain, the variety that is very slow to heal.
