Trying to snap a five-game losing streak, the Cowboys flew to New Meadowlands Stadium for a Week 10 NFC East rematch with the New York Giants.  Dallas trailed in the first quarter as Giants kicker Lawrence Tynes made a 43-yard field goal.  The Cowboys answered with quarterback Jon Kitna connecting to rookie wide receiver Dez Bryant on a 13-yard touchdown pass (with a failed PAT).  Dallas added onto their lead in the second quarter with a 22-yard field goal from kicker David Buehler, followed by rookie cornerback Bryan McCann returning an interception 101 yards for a touchdown and Buehler's 23-yard field goal.  New York answered with Tynes making a 25-yard field goal. The Cowboys continued its dominating day in the third quarter as Kitna found running back Felix Jones on a 71-yard touchdown pass. The Giants responded with quarterback Eli Manning completing a 5-yard touchdown pass to wide receiver Mario Manningham, yet Dallas rebounded with Kitna hooking up with wide receiver Miles Austin on a 24-yard touchdown pass.  However, New York continued its persistent play with Manning completing a 35-yard touchdown pass to tight end Kevin Boss.  Fortunately, the Cowboys' defense held its ground in the fourth quarter to preserve the victory. The game was delayed in the third quarter for about fifteen minutes when the lights at the New Meadowlands Stadium went out.  Since it was already dark outside in New Jersey by that time, it was totally dark in the stadium.
