On the final play of last Sunday's game (that wasn't a kneel down) Charles Woodson injured his shoulder on a tackle attempt. It turned out he had a dislocated shoulder, which was met with a great deal of speculation on his timetable for return.
The estimates as to how long Woodson would be out ranged from being out "an extended period of time" to him not missing a game. As Jack Del Rio explains it, that all depends on the severity of the injury and the player who experiences it.
"When you get hurt, it's serious for the guy that's dealing with it," said Del Rio.
