David Wilson out with neck injury

EAST RUTHERFORD, N.J. -- New York Giants running back David Wilson left Sunday's 36-21 loss to the Philadelphia Eagles with a neck injury and did not return.

Afterward, he tweeted that he was OK.

It was unclear when Wilson suffered the injury. He was heavily involved in the offense in the first quarter, scoring the game's first points on a 5-yard touchdown run, and did a double-backflip in the end zone after that play.

But Wilson got three more carries after that and was targeted once on a pass play. It did not appear as if the backflip had anything to do with the injury.

Wilson's final play of the game was the last play of the first quarter. The play began at the Giants 5-yard line, but the offensive line crumbled and Wilson was hit in the backfield. He was actually pushed back into the end zone, but was not called for a safety because the officials awarded him forward progress at the Giants 2-yard line.

Wilson stayed on the ground for a few moments after the play but headed to the locker room shortly thereafter. When the Giants returned to the field for the second half, they announced that Wilson would not return.

Brandon Jacobs took over running back duties in Wilson's place and finished the first half with 16 yards on four carries. Jacobs also coughed up a costly and unforced fumble in the second quarter that the Eagles recovered and converted into three points with a field goal.

The Giants entered the game ranked 30th in the league in rushing offense at 57.8 yards per game.
