Washington Redskins defensive end Adam Carriker is expected to have surgery on his right knee after seriously injuring it on the second play of Sunday’s 31-28 loss at St. Louis.

Carriker is to have an MRI on Monday to learn the extent of the injury, but Redskins coach Mike Shanahan indicated that the team isn’t optimistic about Carriker’s chances of returning any time soon.

“It doesn’t look good,” Shanahan said.

 The defensive end watched the second half of the game on crutches and said he was still in a lot of pain as he hobbled out of the locker room and to the team bus, still on crutches. 

Meanwhile, outside linebacker Brian Orakpo could be lost for a significant stretch of time as well after re-injuring the same shoulder/pectoral muscle that required surgery in the offseason.

 Orakpo suffered his injury on the 13th play of the game, and tried to return twice,. After two second-half plays, Orakpo left the game for good.

 Shanahan said only that Orakpo had a pectoral injury, but as he left the locker room hurriedly, he said that was on his way to be examined by James Andrews, the physician who conducted his surgery in the offseason.

“It just ripped on me, man,” Orakpo said. “Same injury as before. It’s just frustrating, man.”

 Meanwhile, cornerback Josh Wilson left the game in the second half with a concussion and wasn’t available for comment after the game.
