Both starting guards for the Washington Redskins, Brandon Scherff and Shawn Lauvao, will have season-ending surgery, as will wide receiver Paul Richardson.
Coach Jay Gruden announced Monday that Scherff, a Pro Bowl right guard, tore a pectoral muscle, while Lauvao, a left guard, tore the ACL in his left knee during Washington's 38-14 loss to the visiting Atlanta Falcons.
That setback Sunday ended a three-game winning streak for the NFC East-leading Redskins.
Richardson has been dealing with a shoulder problem that now needs an operation.
Washington already was facing injury problems: Pro Bowl left tackle Trent Williams missed Sunday's game after having surgery on his right thumb and could be out another two or three weeks, Gruden said, while starting slot receiver Jamison Crowder sat out the past four games with a bad ankle.
