San Francisco 49ers running back Raheem Mostert was ruled questionable to return after a knee injury in the first quarter of Sunday’s opener on the road against the Detroit Lions.

After rushing for 20 yards on his first two carries, the oft-injured Mostert was immediately removed from the game after the injury replaced by Elijah Mitchell, who ran 38 yards for a touchdown in the second quarter on his third carry.

JaMychal added a 3-yard TD run later in the second quarter as the 49ers built a 21-10 lead.

Despite being deemed questionable to return, Mostert he was loosening up on the sideline shortly after being replaced.

Niners rookie Trey Sermon, a former Ohio State star running back, was among the club’s innactives for the game.
