Giants add CB Brian Williams

EAST RUTHERFORD, NJ -- The New York Giants signed cornerback Brian Williams on Wednesday to help their depleted secondary.

Williams, who played for the Atlanta Falcons the past two seasons but has battled knee injuries, worked out for the Giants on Wednesday in a group of four corners that included veteran Lito Sheppard.

"Brian Williams, that's one," Coughlin said, hinting that the team could sign another cornerback. "He's a veteran, he knows how to play, he has been a good, physical blitzer. We needed somebody who can learn some things real quick and go from there."

Cornerback Dre' Bly also worked out for the Giants, according to the Newark Star-Ledger.

The Giants waived linebacker Kenny Ingram to make room for Williams on the roster.

Williams joins a Giants team in dire need of a cornerback after losing Terrell Thomas and Brian Witherspoon for the season to torn ACL injuries on Monday night.

The Giants have already lost three cornerbacks for the season in camp, including Bruce Johnson, who ruptured his Achilles early in camp.

First-round pick Prince Amukamara remains out with a broken foot.

The 5-foot-11 Williams, 32, was Atlanta's third cornerback last season. Williams suffered a left knee injury in the Falcons' season finale against the Carolina Panthers and missed the NFC divisional playoff game against the Green Bay Packers. He had 36 tackles and one sack last year.

Williams, who has 19 career interceptions, played in just five games in 2009 before undergoing reconstructive surgery on his right knee.
