The Facts: Kittle is dealing with a sprained MCL in his left knee that would sideline most players for a few weeks, but the belief is that he will be ready to return for Week 3 against the New York Giants, a league source told ESPN.

Diehards Line:An MRI on Monday revealed the damage to Kittle's MCL, but he was spotted around the Niners' training facility this past week walking without a limp, bolstering the belief -- and hope -- that he will be back for Week 3. NFL Network's Ian Rapoport adds that Kittle has a bone bruise to to the knee. Rapoport is also reporting a Week 3 return is likely.
