Mims was waived by the 49ers on Wednesday.
Despite signing Mims in late May, San Francisco has already decided to move on from the running back. The Fresno State product has spent time with the Saints and Titans across his three seasons in the NFL, logging 161 total snaps (101 on offense, 60 on special teams) across 14 contests. In a corresponding move, the 49ers signed running back Sincere McCormick to a one-year deal Wednesday.
