Giants CB Thomas tears ACL

Cornerback Terrell Thomas tore his anterior cruciate ligament Monday, another loss for an already battered New York Giants secondary before the regular season has even commenced.

The injury occurred late in the first half of a preseason game against the Bears. Thomas was coming in on a blitz and had his leg caught underneath a teammate as he tried to deflect a Jay Cutler pass.

After several moments on the ground, Thomas got to his feet and walked off the field under his own power, albeit gingerly.

Thomas has been a fixture in the Giants' defensive backfield the past two years and was credited with 81 solo tackles last year. He also picked off five passes for the second consecutive season.

The Giants selected Thomas in the second round of the 2008 draft out of USC.

The incident comes two weeks after rookie cornerback Prince Amukamara suffered a fracture of the fifth metatarsal bone in his left foot.
