Mostert (knee) is listed as active Monday versus the Seahawks.
Mostert has been dealing with a knee injury for the better part of the last month but still played in each of the 49ers' last three games. His only noticeable impact during that stretch occurred on a 41-yard touchdown run Week 8 as he continues to play a bit role behind Tevin Coleman and Matt Breida. Expect Mostert to be mostly contained to special teams yet again in Week 10.
