Report: 49ers' Jeff Wilson to miss 4-6 months after meniscus surgery

San Francisco 49ers running back Jeff Wilson is expected to be out four-to-six months after undergoing surgery to repair a torn meniscus, sources told NFL Network's Mike Garafolo.

The timetable means Wilson will likely miss the beginning of the regular season.

Wilson led the 49ers in rushing with 600 yards and seven touchdowns last season, drawing a heavier workload as other runners went down with injuries. He's spent his entire three-year career in San Francisco after going undrafted in 2018.

The 49ers reinforced their backfield earlier in the offseason, signing Wayne Gallman from the New York Giants in free agency and selecting Trey Sermon out of Ohio State in the third round of the NFL draft. Raheem Mostert, who averaged a team-high five yards per carry in 2020 but missed eight games with injuries, is due back as well.
