Carroll also missed three games in 2008 because of an ankle injury.
When he's played, though, Carroll has shown he can be an effective cover corner, and the fact he served as a team captain last season speaks well of his leadership abilities.
Carroll began his career at Maryland as a wide receiver before being switched to cornerback and he's also done solid work on special teams.
Before the injury, Carroll reportedly was timed in 4.37 40-yard dash, so he's obviously got speed.
Carroll, who stands 6 feet, 205 pounds, has been projected as being drafted anywhere from the third to the seventh round. He's one of those guys who really could help himself in workouts between now and the draft.
