The news comes after Guerendo initially suggested that his removal from the end of the blowout against the Bears was a precautionary measure. After initial ambiguity surrounded the health of Guerendo following his instant-impact performance in Week 14, it’s been confirmed that the 49ers running back is dealing with a foot sprain. The exact extent of the injury remains unclear at this point, but HC Kyle Shanahan didn’t rule out Guerendo for the team’s divisional clash against the Rams on Thursday night. However, the team’s plan to monitor his health over the next few days doesn’t exactly sound like a glowing report on his status, either. Had the 49ers’ next game been on a Sunday and not a Thursday, there would likely be a much higher probability that we see Guerendo suit up for the 49ers as they look to claw their way into the playoffs. However, fantasy managers who scooped him up off the waiver wire last week and reaped the benefit this week could be without their newest toy in the first week of the fantasy football playoffs. In the meantime, if Guerendo is ultimately ruled out, fantasy managers can set their sights on Patrick Taylor and Izzy Abanikanda to help weather the storm that’s eviscerated the depth in the 49ers backfield.
