Barnett tears MCL; Orakpo day to day

ASHBURN, Va. -- Washington Redskins linebacker Nick Barnett suffered a third-degree tear of his left medial collateral ligament and won't play in the season finale against the New York Giants. Barnett will need six weeks to recover from the injury.

Barnett injured his knee on Dallas' 62-yard punt return in the first quarter of the Redskins' 24-23 loss. Barnett had arthroscopic surgery on his right knee after last season. He was signed only for 2013. But the positive for Barnett is that it's unlikely he'll need surgery, coach Mike Shanahan said.

Meanwhile, linebacker Brian Orakpo, who injured his right groin, is day to day. Shanahan said they'll have a better feel for his status by Wednesday.

The Redskins called up Will Compton to take Barnett's roster spot. They still have one more roster spot available after putting tight end Jordan Reed on injured reserve. Shanahan said they'll likely make a move Wednesday to fill that spot.
