Giants' Webster to sit Sunday

East Rutherford, NJ (SportsNetwork.com) - The New York Giants will be without cornerback Corey Webster for the third straight game because of a groin injury.

Webster had been listed as doubtful for Sunday's game against Philadelphia after missing practice Thursday and Friday.

The Giants are already down a cornerback after Aaron Ross was placed on injured reserve because of a back injury.

Center David Baas (neck) and defensive tackle Linval Joseph (ankle/knee) had already been ruled out on Friday.
