Mitchell (knee) is seeking to return to action in Week 10 against the Chargers, Matt Maiocco of NBC Sports Bay Area reports.
Mitchell has been sidelined since spraining the MCL in his right knee in the season opener. Since then, the 49ers rode Jeff Wilson in the backfield until the recent acquisition of Christian McCaffrey. After two games with McCaffrey on the roster and Mitchell getting healthier by the week, the team opted to deal Wilson to the Dolphins, paving the way for Mitchell to be the No. 2 running back once he's healthy. In that regard, he'll have the benefit of a Week 9 bye. How he fares on the field next week, assuming he does get designated to return from IR, will determine whether or not he joins McCaffrey as an RB option for coach Kyle Shanahan in Week 10.
