SANTA CLARA, Calif. (AP) — The San Francisco 49ers have placed star cornerback Richard Sherman on the injured reserve list and also could be without All-Pro tight end George Kittle this week.
Sherman strained his calf late in the opener and was placed on IR when the injury didn't get better right way.
He will have to miss at least three games.
Sherman should be back in time for the Seahawks game in Week 7.
Kittle sprained his knee in the same game and won't take part in a full practice this week but could still play against the Jets.
