Mostert (ankle) is listed as questionable for Thursday's contest versus the Raiders.
Mostert wrapped up Week 9 preparations with back-to-back limited walk-through participation, making him a decent candidate to work in a reserve role behind Matt Breida (ankle) on Thursday. Considering Mostert is a bit banged up at the moment, the 49ers may follow a similar breakdown of snaps for Breida (47 percent of the offensive snaps), Mostert (18.2 percent) and Alfred Morris (16.7 percent) to what they deployed in the Week 8 loss to Arizona.
