There is nothing to worry about here as the 49ers will be managing Kittle's practice reps for the rest of the season. He is going to need to stay off his ankle for weeks for it to fully heal, and may even be a candidate for offseason surgery. Kittle was held in check against a ferocious Ravens defense, but the game was played in the rain, and the 49ers leaned on the ground game throughout the tightly contested loss. Kittle should be able to bounce back against a Saints defense dealing with enough injuries at linebacker to warrant signing Manti Te'o off the street. Barring a serious aggravation, Kittle will play through the injury for the rest of the season at a top tier TE1 level.
