Coming off their home win over the Ravens, the Giants flew to the University of Phoenix Stadium for a Week 12 duel with the Arizona Cardinals.  In the first quarter, New York trailed early as Cardinals kicker Neil Rackers got a 34-yard field goal.  In the second quarter, the Giants responded with RB Derrick Ward getting a 1-yard TD run.  Arizona would answer with RB Tim Hightower getting a 4-yard TD run (with a failed extra-point attempt).  New York replied with kicker John Carney getting a 33-yard field goal, yet the Cardinals got the lead again as Rackers made a 20-yard field goal.  The Giants would regain the lead prior to halftime as QB Eli Manning completed a 12-yard TD pass to WR Amani Toomer. In the third quarter, the G-Men increased their lead as Manning completed a 2-yard TD pass to FB Madison Hedgecock.  Arizona would answer with Hightower's 1-yard TD run.  In the fourth quarter, New York greatly increased their lead as Manning completed a 10-yard TD pass to TE Kevin Boss. Following an interception by Terrell Thomas, John Carney got a 27-yard field goal.  Arizona would respond with QB Kurt Warner completing a 5-yard TD pass to WR Anquan Boldin, yet the Giants answered with Carney getting a 33-yard field goal.  The Cardinals tried to come back as Rackers nailed a 44-yard field goal.  Fortunately, New York recovered the following onside kick and prevailed. On Friday, November 28, 2008, Giants Wide Receiver Plaxico Burress suffered an accidental self-inflicted gunshot wound to the right thigh in a New York City nightclub when his gun, tucked in the waistband of his sweatpants, began sliding down his leg. The injury was not life-threatening and he was released from an area hospital the next afternoon. The following Monday, Burress turned himself in to police to face charges of criminal possession of a handgun. Burress had an expired concealed carry (CCW) license from Florida, but no New York license. On December 2, 2008, Burress posted bail of $100,000.  He was scheduled to return to court on March 31, 2009, to enter a plea.  Later in the day, Burress reported to Giants Stadium as per team policy for injured but active players, and was told he would be suspended without pay Burress would later be released by the Giants on April 3, 2009.
