Isaac Guerendo

Isaac Guerendo (foot) is questionable for Week 15 against the Rams.

Guerendo was held out of the first two practices after suffering a sprained foot in the 49ers’ Week 14 win over the Bears. He returned for a limited session on Wednesday. With both Jordan Mason and Christian McCaffrey on injured reserve, Guerendo was the next man up last week, though that didn’t last long. If he can’t suit up tomorrow, Patrick Taylor will be the latest runner to take over the San Francisco backfield. He would sit in the RB2 ranks with Guerendo out.
