The Giants opened up their 2007 campaign with a 45-35 loss to the Dallas Cowboys at Texas Stadium.  For the second straight year, the Giants left Dallas with injuries to key starters including DE Osi Umenyiora, RB Brandon Jacobs, and QB Eli Manning.  Before suffering a separated shoulder in the fourth quarter, Manning put on a stellar performance, completing 28 of 41 passes, for 312 yards, 4 touchdowns and just 1 interception.  However, a horrid defensive performance overshadowed Eli's play. The Giants got off to a fast start as Eli hit Plaxico Burress on a 60-yard touchdown pass off play action to open up the scoring.  Burress and Manning would connect for 3 touchdowns on the night.  After a Dallas took a 17-6 lead late in the half, Eli led the Giants on another  drive, capped off to his second strike to Burress.  Burress on the night caught 9 passes for 144 receiving yards.  The Giants closed to within one at half's end following a Lawrence Tynes field goal after a Dallas fumble. Romo hit Terrell Owens on a 22-yard pass to give Dallas an 8-point lead.  After the Giants cut the lead to five on another Tynes field goal, Dallas increased the margin to 12 as Romo capped off a quick four play drive with a 9-yard rush.  The Cowboys appeared to put the game away with yet another Romo touchdown, once again finding Terrell Owens on a wide open catch and run, upping margin to 38-22.  Eli and the Giants responded with two straight scoring drives.  One finished with a dumpoff touchdown pass from Manning to reserve running back Derrick Ward and the other with Burress' 3rd touchdown, cutting the Dallas lead to three. On a crucial 3rd and seven late in the game, Romo hit backup wideout Sam Hurd for a 51-yard touchdown.  With Manning injuring his shoulder, backup Jared Lorenzen finished the game for the Giants at quarterback late in the fourth quarter. Amani Toomer in his return from a  knee injury, notched 9 catches for 91 yards while Burress gained 144.  Justin Tuck and Gibril Wilson recorded the Giants' only sack and interception of the night respectively in the 45-35 loss as the Giants began the season at 0-1. It would be the only road loss for the Giants in the season.
