New Orleans Saints CB P.J. Williams carted off with neck injury

EAST RUTHERFORD, N.J. -- The New Orleans Saints, already thin at cornerback, may have lost another member of their secondary in Sunday's game against the New York Giants.

Cornerback P.J. Williams, a second-year player out of Florida State, suffered a neck injury on a first-quarter tackle of Giants tight end Larry Donnell with 6:15 left in the quarter.

Williams' head made contact with Donnell's right knee. Then teammate Craig Robertson's leg hit Williams' head, causing his neck to whiplash a second time.

Williams head violently snapped to the side, as he fell to a crumpled heap on the turf, the players immediately calling for medical officials.

Williams was placed on a backboard, his neck stabilized as he was carted off the field for further evaluation. The Saints announced he is being evaluated for a concussion but had movement in his extremities.
