Washington Redskins guard Brandon Scherff is thought to have suffered a torn pectoral muscle Sunday against the Atlanta Falcons, sources told NFL Network's Ian Rapoport.
The two-time Pro Bowler will undergo an MRI.
Scherff was pulled from Sunday's 38-14 loss, along with fellow guard Shawn Lauvao, who left in the first quarter due to a knee injury.
Six-time Pro Bowl tackle Trent Williams is reportedly expected to miss "about a month" after undergoing thumb surgery.
Washington visits the Tampa Bay Buccaneers in Week 10.
