Hoping to build on their win over the Houston Texans, the Cowboys stayed at home for a Monday Night match-up with their NFC East rival, the New York Giants.  On the Giants opening drive, Eli Manning threw a 50-yard touchdown to Plaxico Burress.  Later in the first quarter after Jeff Feagles punted inside the one-yard line, LaVar Arrington sacked Drew Bledsoe in the endzone for a safety. In the second quarter, Giants kicker Jay Feely kicked a 31-yard field goal.  Dallas would score before halftime as Bledsoe ran 1-yard touchdown on a quarterback sneak.  Bledsoe also threw a costly interception just before halftime that would have given the Cowboys a 14-12 lead at the break.  Due to Bledsoe's abysmal performance, head coach Bill Parcells replaced him with backup quarterback Tony Romo at the start of the second half.  Not much had changed for the Giants in the third quarter as Manning threw a 13-yard touchdown pass to Jeremy Shockey and Brandon Jacobs got a 3-yard touchdown run.  In the fourth quarter, the Romo completed an 8-yard TD pass to WR Terrell Owens, and Romo ran into the endzone for a two-point conversion.  The Giants pulled away as Feely kicked a 32-yard field goal, while rookie cornerback Kevin Dockery would return an interception 96 yards for a touchdown.  Even though Romo threw a 53-yard touchdown to Patrick Crayton, the damage had already been done.
