Fautanu injured his knee during Friday's practice session and will not play Sunday against the Chargers, Adam Schefter of ESPN reports.
Fellow tackle Broderick Jones told reporters after Friday's practice that Fautanu had "a little tweak" in his knee and is set to undergo an MRI to evaluate the severity of the injury, per Brooke Pryor of ESPN.com. Fautanu made his NFL debut in Week 2 against Denver as he supplanted Jones for the starting right tackle job, but the former will be now sidelined for the foreseeable future. It's unclear whether the knee Fautanu injured Friday is the same knee in which he sustained an MCL sprain during training camp.
