In the first quarter, Buffalo struck first as wide receiver Terrell Owens got a 29-yard touchdown run.  The Texans would answer in the second quarter with a 42-yard and a 22-yard field goal from kicker Kris Brown.  The Bills would end the half with kicker Rian Lindell's 21-yard field goal. Houston would creep closer in the third quarter with Brown booting a 26-yard field goal.  In the fourth quarter, the Texans would take the lead and never look back as running back Ryan Moats got three touchdown runs of 11 yards (followed by quarterback Matt Schaub's 2-point conversion pass to wide receiver Andre Johnson), 1 yard, and 3 yards.

PROBLEM: Passage: The division-leading Dallas Cowboys and Terrell Owens handed the Eagles a decisive 38-17 loss on Sunday night football in Philadelphia. Julius Jones powered into the end zone from two yards out on Dallas' opening drive, but Brian Westbrook answered with a short touchdown of his own after a 45-yard reception by Reggie Brown gave the Eagles' first-and-goal. Then Tony Romo took over, hitting Tony Curtis for a short passing touchdown. Marion Barber III carried it in from five yards out for Dallas after Donovan McNabb was intercepted by the Cowboys' defense. Romo connected with Owens for a 45-yard bomb in the third quarter, making the score 28-7 Dallas. After a David Akers' field goal, Romo got his third touchdown on a 20-yard pass to tight end Jason Witten. McNabb finished the scoring with a 10-yard touchdown pass to Hank Baskett. McNabb passed for a touchdown and 264 yards, but also two interceptions. Westbrook racked up 156 all-purpose yards in another strong showing. Owens burned the Eagles' defense for 174 receiving yards. Philadelphia fell to 3-5 and the team was largely uncompetitive against the Dallas squad.
