Sermon ran for 89 yards on 19 carries against Seattle on Sunday.
The 49ers were without Elijah Mitchell (shoulder) and JaMycal Hasty (ankle), so there wasn't much competition for Sermon in the 49ers backfield Sunday, but Jacques Patrick (two carries) was the only other 49ers running back to touch the ball against Seattle. Given that Sermon mostly did well with the heightened workload, it's possible that he's earned himself more traction in the 49ers backfield even when Mitchell returns. Sermon should probably be considered the favorite to lead the 49ers running backs during next week's clash in Arizona.
