49ers running back Frank Gore left the game Sunday against Minnesota with a right ankle injury. The team says X-rays showed no broken bones and his return is doubtful.
Gore has been bothered by the injury since last week against Seattle. He rushed for 207 yards on 16 carries in the game, but did not play for most of the fourth quarter after getting hurt.
He left the game after rushing for 4 yards on one carry on the second possession of the game for San Francisco. Gore limped to the sidelines and tried to walk it off for several minutes before taking a cart to the locker room.
Glen Coffee replaced Gore as the 49ers primary running back.
