LANDOVER, Md. - Redskins linebacker Brian Orakpo injured his right pectoral muscle in Washington's 19-17 victory over the Tennessee Titans and will have an MRI on Monday.

Orakpo, a three-time Pro Bowler, was hurt trying to make a tackle on a running play in the fourth quarter Sunday and did not return.

Redskins coach Jay Gruden said Orakpo's injury was the only significant one for the team.

Orakpo has twice torn the pectoral muscle near his left shoulder in the past.
