In contrast to the teams' previous meeting, the grand opening of Cowboys Stadium (in front of the largest regular-season crowd in NFL history) was a fast-paced shootout. The first points in the Cowboys' new home were scored by Tynes, whose 30-yard field goal in the first quarter was his first of four on the night. The Cowboys responded by scoring their first points on the ensuing drive&#8212;a 2-yard run by running back Marion Barber. Giants rookie cornerback Bruce Johnson scored his first career points returning a Tony Romo interception 34 yards. Cowboys tight end Jason Witten responded with a 1-yard touchdown pass in the second quarter. Later, Giants safety Kenny Phillips caught an odd interception off Witten's foot, setting up quarterback Eli Manning's 100th career touchdown pass&#8212;a 22-yard strike to Manningham. Romo ran a quarterback sneak to open the scoring in the second half, but the Giants sent wide receiver Steve Smith into the end zone in the fourth quarter. The Cowboys punched in one more touchdown on a 7-yard Felix Jones run, but Tynes' 37-yard field goal as time expired was enough to postpone the Cowboys' first home win in Arlington and boost the Giants to 2-0. The Giants lost two more notable players to injuries; defensive end Justin Tuck suffered a sprained shoulder and wide receiver Domenik Hixon sprained a knee. During the week, Phillips' season was brought to an end, as he was placed on injured reserve with patellofemoral arthritis.
