The San Francisco 49ers' 53-man roster was pretty healthy in the first two weeks of the season. However, the 49ers limped out of their 29-3 defeat at Seattle.Nose tackle Ian Williams broke his ankle and was lost for the season. We may see the affects of the loss at practice this week. Standout tight end Vernon Davis tweeted late Tuesday night that he needs to rest his hamstring (which was injured later Sunday), but he should be able to play Sunday against Indianapolis.
