Mostert (knee) was a limited practice participant Wednesday, David Furones of the South Florida Sun Sentinel reports.
Head coach Mike McDaniel said earlier Wednesday that he expects Mostert to return for Sunday's game in San Francisco against his former team after missing the Dolphins' Week 12 win over Houston. It'll also be a return to San Francisco for McDaniel and fellow running back Jeff Wilson, who took 78 percent of the snaps before halftime in Sunday's 30-15 win over Houston before handing things over to Myles Gaskin once the Dolphins built a huge lead. Wilson is unlikely to handle to handle such a large snap share if Mostert returns this week, but Wilson was getting more work between the two before Mostert's knee injury popped up.
