Isaac Guerendo Believed To Have Foot Sprain

49ers HC Kyle Shanahan said after Sunday's win over the Bears that RB Isaac Guerendo is believed to have a foot sprain. X-rays were not conclusive, and Guerendo is scheduled for more testing on Monday. We should get another update on his status within the next 24 hours, but this injury could certainly cost him time. Guerendo's absence would leave Patrick Taylor as San Francisco's latest lead back.
