The Giants can add yet another name to their already extremely long injury list.  Cornerback Prince Amukamara was carted off the field yesterday and has been diagnosed with a high ankle sprain after making a tackle on wide receiver Brandon Marshall.  The Giants have had a lot of problems at the position, Amukamara was filling in for injured Terrell Thomas.  Thomas actually tore his ACL in a preseason game against the Bears last year.  Prince's replacement, Bruce Johnson, did not fair well after missing coverage on Marshall and allowing a touchdown on his first play of the game.  The Giants are hoping that rookie Jayron Hosley will be ready in time for the season opener, but he is currently sidelined with a turf toe injury an the Giants do not want it to become something more serious.  It will be interesting to see how the Giants fill the void.  Last year, they choose to go with a nickel defense and safety Antrel Rolle would play the role.  Linebacker Mathias Kiwanuka also suffered an injury, but said that he would definitely be ready for the season opener.  "I feel good," Kiwanuka said. "I dont think it's anything serious, nothing that should affect me for the beginning of the season."   The night was not all bad, however.  One player who is looking for a spot on the roster, Da'Rel Scott impressed last night. He had the biggest play of the night with a punt block in the second quarter.  It allowed the Giants to set up for a touchdown on the Bears ten yard line and give the Giants a 17-7 lead.  The Giants also got to see another impressive game from rookie David Wilson.  Wilson finished the game with 75 yards, but it was his ability to get first downs that was the significant part.  Eli Manning also finished strong, completing 17 of 21 passes for 148 yards in the first half.  Hakeem Nicks suited up for the game, but did not enter the game.
