The San Francisco 49ers have placed George Kittle on injured reserve, ruling the tight end out for at least three games due to his calf injury.
Kittle has been playing through the injury since suffering it in Week 1 against the Detroit Lions. But he did not participate in practice all week and had been considered doubtful for Sunday's game against the Arizona Cardinals prior to the IR move.
It's another major change to the 49ers offense, which will start rookie Trey Lance at quarterback for the first time with Jimmy Garoppolo out with a calf injury as well.
