49ers RB Isaac Guerendo tore his pectoral lifting weights about a month ago and could return “around the end of training camp.”

49ers head coach Kyle Shanahan broke the news this afternoon. This is a bummer. Earlier this month, The Athletic’s Vic Tafur said he believed Guerendo was “buried” on the depth chart and will likely “be looking for a new team” at some point. The team could end up releasing him with an injury settlement, but we suppose some sort of reserve list placement is possible. 49ers RBs Jordan James and Kaelon Black can be expected to compete for RB2 duties at this time. The team also signed RBs Jordan Mims and Jermar Jefferson today.
