Prince Amukamara out with groin strain

INDIANAPOLIS -- Cornerback is the deepest position group the New York Giants have, but it may be a bit thinner for a while. Starting corner Prince Amukamara left Saturday's preseason game against the Indianapolis Colts with a groin strain, the team announced in the second quarter. He will not play for the remainder of the game.

Amukamara is having a strong preseason and is slated to start for the Giants opposite Dominique Rodgers-Cromartie. But the Giants are deep at cornerback and have options to replace Amukamara if he's out for a while.

Walter Thurmond has been playing the nickel corner position for the Giants but is capable of playing outside if need be, and indeed Thurmond was playing outside corner in the second quarter Saturday night after Amukamara's exit. The Giants can replace Thurmond in the slot (or Amukamara on the outside, for that matter) with Trumaine McBride, who was a starter for them last year and was making his 2014 preseason debut Saturday night after missing the first two games as he recovered from offseason hip surgery.

The Giants also signed free-agent cornerback Zack Bowman, formerly of the Bears, in the offseason and could give a longer look to Charles James, who still harbors hope of making the team at a crowded position.
