at the Georgia Dome, Atlanta, Georgia Coming off their season-sweep in Tampa over the Buccaneers, the Falcons went home for a crucial Saturday night fight with the Dallas Cowboys.  In the first quarter, Atlanta trailed early with Cowboys QB Tony Romo completing a 7-yard TD pass to WR Terrell Owens for the only score of the period.  In the second quarter, Dallas' lead increased with OLB returning an interception 41 yards for a touchdown on the very first play of the period.  Fortunately, the Falcons fought back with QB Michael Vick throwing a 1-yard TD pass to FB Justin Griffith and a 9-yard TD pass to WR Michael Jenkins.  It was after the second touchdown that an NFL record was set.  After kicker Morten Andersen's extra point, he became the league's all-time leading scorer with 2,435 points.  His total after the game would be 2,437 points. After Atlanta's second score of the game, the Cowboys jumped back into action, with Romo completing a 51-yard TD pass to Owens.  Fortunately, the Falcons managed to tie the game going into halftime with Vick's 8-yard TD pass to WR Ashley Lelie.  In the third quarter, Atlanta took the lead with Vick's 5-yard TD pass to Griffith.  However, the joy was short-lived as Dallas took over for the rest of the game with kicker Martin Gramatica's 48-yard field goal and RB Marion Barber's 9-yard TD run.  In the fourth quarter, the Cowboys wrapped up the game with Barber's 3-yard TD run.  With the loss, the Falcons fell to 7-7. Fortunately, not all was bad.  Along with Andersen's record-setting night, Vick also managed to set a record for the most single-season rushing yards by a quarterback with 934 yards at game's end and would appear in only one more game.  Also, the entire Falcons rushing corps broke the single-season rushing record that they set two seasons ago (which was 2,672) with a new record of 2,697 yards.
