Mitchell (knee) won't participate in Wednesday's practice, Matt Maiocco of NBC Sports Bay Area reports.
Once again, the 49ers are placing practice limitations on Mitchell due to the knee injury that has bothered him since early December. He hasn't had any problem playing through the issue, earning most of the snaps given to 49ers running backs over the last four contests. During that stretch, Mitchell has averaged 23 touches for 92.8 yards from scrimmage per game while scoring two touchdowns. He'll look to mix into drills Thursday and/or Friday and enter the weekend without a designation for Sunday's NFC Championship Game at the Rams.
