Washington linebacker Ryan Kerrigan left late in Monday night's game against the Eagles with a possible concussion. He was the only player to suffer a potentially serious injury, though his status is not yet known.

Kerrigan left the game late in the fourth quarter and did not return. He was taken to the locker room for further evaluation. During his postgame press conference, head coach Mike Shanahan said Kerrigan was still being evaluated.

Beyond Kerrigan, Washington didn't suffer any significant injuries. A few players left the game with leg cramps, including wide receiver Pierre Garcon, but he later returned to the game. Return man Chris Thompson left the game with an ankle injury, although Shanahan said after the game he thought Thompson was OK.

The Eagles didn't appear to deal with any major injuries. Cornerback Bradley Fletcher left the game during the fourth quarter, although he was able to walk off on his own. Left tackle Jason Peters left the game due to a hand injury, but returned after being examined by the medical staff.

A few players returning from injury managed to make it through Monday's game healthy. Robert Griffin III didn't have his best game, but didn't appear to be hampered by the knee injury he suffered last year. Although LeSean McCoy was nicked up last season, he looked 100 percent healthy, racking up 184 rushing yards.
