49ers coach Kyle Shanahan said RB Raheem Mostert has a high sprained left ankle. He's expected to miss time, will "most likely" go on IR.
Mostert will miss at least three weeks if placed on IR. Tevin Coleman is still out which will leave Wilson, McKinnon and Hasty to take over. McKinnon has struggled as of late so it could be a hot-hand situation has Hasty looks to make a name for himself.
