Coach Kyle Shanahan said the decision to use Mostert rather than Alfred Morris as the top complement to starter Matt Breida in Monday's 33-30 loss to the Packers wasn't necessarily a "permanent" move, Cam Inman of The San Jose Mercury News reports.
Mostert appears to have gotten the nod over Morris based on the matchup more than anything, but the 26-year-old impressed thoroughly with his touches. Working in tandem with Breida -- who earned 14 carries on 27 offensive snaps -- Mostert used 23 snaps to churn out 87 yards on his 12 rushes. With an upcoming matchup Sunday against the Rams, it remains to be seen if the 49ers will return to their previous one-two punch of Breida and Morris or deploy the most recent version.
