49ers injury update: Raheem Mostert questionable to return vs. Lions

#49ers RB Raheem Mostert is questionable to return vs. the Lions.

After only two carries, 49ers running back Raheem Mostert is already dealing with a knee injury. He had 20 yards in his two touches and looked explosive. There was no real indication of when he might’ve gotten hurt, but now he’s questionable to return to the contest.

The 49ers only have two other active running backs.  They are second-year undrafted free agent JaMycal Hasty, and rookie sixth-round pick Elijah Mitchell.
