Brian Orakpo has suffered a torn right pectoral muscle and will miss the remainder of the season.
Team officials told ESPN.com on Sunday night that they feared this outcome.
It's the third time he's torn a pectoral muscle, though the first two were on the left side, with one of those tears costing him the final 14 regular-season games in 2012.
Orakpo's tenure with Washington could be over.
