The Facts: The 49ers are placing Kittle (calf) on injured reserve, meaning he's out three games.

Diehards Line: Kittle had been listed as doubtful against the Cardinals. The 49ers have a bye next week, but the modified IR rule is written as a player must miss three games, not three weeks, so the soonest Kittle can return is the Week 9 against Arizona. Rather than having the injury nag him all season, the hope is it settles down and he can be back when eligible. The expectation is he'll be ready.
