We assumed the 49ers backfield would be crowded heading into Week 1 of the regular season with as many as six capable running backs. Well, that took a hit as NFL Network’s Mike Garafolo reported that running back Jeff Wilson Jr. recently underwent surgery to repair a torn meniscus.
Wilson is expected to miss four to six months, which would keep him sidelined through at least the first month of the season. The reason for the extended injury timeline is because Wilson’s meniscus needs to be repaired. If it were a scope or a trim, Wilson would return between 3-6 weeks.
