It was initially believed that the injury was just an aggravation of a previous pectoral tear and would only keep the linebacker out for a week or so, but Shanahan told the media on Monday that Orakpo had torn the muscle in a different location than was operated on over the offseason. He will require another surgery, ending his season.
Shanahan announced that the two-time Pro Bowl linebacker will undergo surgery this week and the team is expecting a four-month recovery period that will keep the fourth-year pro out of action for the rest of 2012.
Shanahan says the team will miss Orakpo's production on defense. "He can do it all. He's everything you look at in a Pro Bowl linebacker."
The Redskins will use Rob Jackson and Chris Wilson in that linebacker position when they take on the Cincinnati Bengals in Washington's home opener on Sept. 23.
Orakpo left the game after sacking Rams' quarterback Sam Bradford and was seen on the sidelines without his shoulder pads. Orakpo returned to the game shortly but then left for good. The pectoral has been a problem for Orakpo before, forcing him to have surgery earlier this year.
The Redskins are expected to keep the fourth-year pro out in an attempt to prevent any further aggravation of the injury. Redskins' coach mike Shanahan is expected to address the media at 3 p.m. ET and provide further information on his injury status. The pass-rushing linebacker is set to miss at least one game, counting him out of the Redskins' home opener against the Cincinnati Bengals on Sept. 23.
Washington Redskins linebacker Brian Orakpo left the field during Sunday's game against the St. Louis Rams after suffering an injury to his arm and shoulder area. Orakpo walked to the sideline and threw off his helmet in frustration after sacking Rams quarterback Sam Bradford.
Orakpo was seen with his shoulder pads off, sitting on the sideline as he was being attended to by the team's training staff. The fourth-year player out of Texas has missed just one game in his NFL career up to this point. He has 28.5 sacks out of his pash-rushing linebacker position since coming to the Redskins.
The Redskins are currently on top of the Rams, 7-3, in the first quarter of play at the Edward Jones Dome.
UPDATE: Orakpo has returned to the game.
[Note by Ryan Van Bibber, 09/16/12 5:05 PM EDT ] And then he was out again. It's a shoulder injury, and his return is being called questionable.
Redskins calling Orakpo's injury a shoulder strain. Say his return is questionable.
