Isaac Guerendo

49ers coach Kyle Shanahan said Isaac Guerendo has a sprained foot, and the team will “evaluate him over the next few days” to determine his Week 15 availability.

An MRI confirmed previous suspicions that Guerendo suffered a sprained foot in Sunday’s win over the Bears. Now, the 49ers will see if the rookie can overcome a short rest week in time to suit up for Thursday night’s game against the Rams. The 49ers need all hands on deck as the look to make a late postseason push, but four days of rest may not be enough time for Guerendo to get right. He’ll likely be listed as a DNP on the team’s estimated practice report on Monday, but Tuesday and Wednesday will be something to monitor as the team prepares for the divisional matchup. If he can’t play, Patrick Taylor would be next in line to lead the 49ers’ backfield.
