Six days after losing at home, Tony Romo made his first NFL regular season start against the Carolina Panthers, and he threw for 270 yards, a touchdown, and an interception.  In the first quarter, the Panthers scored 14 points when DeShaun Foster, and later Steve Smith ran a touchdown, but those were the last points that Dallas allowed in the game.  In the second quarter, Jason Witten caught a touchdown pass and Mike Vanderjagt kicked a field goal.  In the fourth quarter, Dallas scored a franchise record 25 points on a Julius Jones run, two Marion Barber runs, another Mike Vanderjagt field goal, two extra points and a two-point conversion caught by Terrell Owens.  Terrell Owens had his first 100+ yard game with 107 receiving yards.  Julius Jones ran  92 yards for 616 yards in 7 games to start the season.  Steve Smith was held to only 55 receiving yards and former Cowboys receiver Keyshawn Johnson only had one catch for 19 yards.  The game marked unusual emotion from Bill Parcells, who was moved by the appearance of his former Giants players (such as Jim Burt) and who embraced many of his players late in the game.
