Raheem Mostert played 23 offensive snaps and produced career-highs with 12 rushing attempts for 87 yards. Mostert was rewarded with playing time behind Matt Breida that had previously been designated for veteran Alfred Morris.
Morris got just one snap on Monday night. The story said Mostert was challenged by HC Kyle Shanahan after Breida went down in Week 5, but Mostert fumbled on his first attempt. Shanahan called out Mostert for that fumble in front of the team, and it looks like he responded with a very good game against the Packers. The performance now casts a lot of doubt on Morris' fantasy value going forward.
