Mostert rushed four times for 26 yards and a touchdown Sunday, but he did the majority of his damage on two receptions for 104 yards and another score in a preseason win over Minnesota.
Mostert's big night puts him in a strong position to win one of the 49ers' final roster spots heading into the season. The 25-year-old has now surpassed the century mark in both rushing (115 yards) and receiving (104 yards) -- albeit against backup defenders -- through two preseason contests. If Mostert makes the cut, he would sit low on the running back depth chart and make the majority of his contributions on special teams.
