In the first quarter, Detroit trailed early as Eagles RB Brian Westbrook ran 25 yards for a TD.  The Lions tied the game on a Kevin Jones 2-yard TD run, but Philadelphia regained the lead with a Westbrook 5 yard TD run, along with QB Donovan McNabb's 68-yard TD pass to WR Kevin Curtis.  In the second quarter, the points bonanza continued as McNabb and Curtis hooked up with each other again on a 12-yard TD pass and a 43-yard TD pass to increase the Eagles' lead.  Detroit responded with QB Jon Kitna completing TD passes of 11 yards to WR Shaun McDonald and 91 yards to WR Roy Williams.  Philadelphia capped the half with McNabb completing a 43-yard TD pass to Westbrook. In the second half, the Eagles took control as RB Correll Buckhalter ran 1 yard for a TD run in the third quarter and RB Tony Hunt ran for a 1-yard TD in the fourth quarter.
