Jeff Wilson will miss start of 2021 season with torn meniscus

San Francisco 49ers running back Jeff Wilson will miss four to six months with a torn meniscus (per Mike Garafolo)

Fantasy Impact: Wilson was the 49ers top back last year leading the team in rush attempts, rush yards, touchdowns, and finished RB30 in .5PPR. With Wilson injured, the 49ers backfield will come down to Raheem Mostert and rookie Trey Sermon for the starting gig in Week 1. Both their arrows are pointing up with this news.
