SANTA CLARA, Calif. (AP) - San Francisco 49ers running back Frank Gore is expected to miss three weeks because of a right ankle strain.
The 49ers said Monday night that the strain was revealed during an MRI.
Gore injured the ankle on his only carry during Sunday's 27-24 loss to the Minnesota Vikings. He left the game after a four-yard gain and did not return.
Gore was taken to the locker room on a cart but X-rays revealed no broken bones.
The team says it is not related to the ankle sprain he sustained during his 207-yard rushing performance against the Seattle Seahawks on Sept. 20.
The 49ers also said tackle Joe Staley is day to day with a bruised right thigh and safety Reggie Smith has a strained right groin that will be re-evaluated in two weeks.
