Eagles running back LeSean McCoy left Philadelphia's 31-6 loss to theWashington Redskins in the fourth quarter with a concussion.

McCoy was carrying the ball with 1:45 left in the game trailing 31-6.  The question was asked to Andy Reid why McCoy was even in the game at that point.

"I was just trying to catch up and win the game," explained Reid.

McCoy was taken off the field on a cart after staying down following a 7-yard run with less than 2 minutes left Sunday.

Citing a source close to McCoy, the Philadelphia Inquirer beat reporter Jeff McLane reports the Eagles' running back is "alert," but "foggy and tired" after suffering his concussion.

He ran for 45 yards on 15 carries and gained another 67 yards on six catches.

McCoy entered the game with 702 yards rushing on 162 carries this season.

Tight end Brent Celek was checked for a head injury but passed tests and was deemed OK.

The Eagles (3-7) have lost six games in a row.
