Beginning a three-game NFC East road trip, the Eagles hung on to sweep the Washington Redskins 21-19.  Washington was able to run the ball all day and Ladell Betts, who finished with 171 rushing yards, led the Redskins to a 3-0 lead after their first drive with kicker Shaun Suisham getting the field goal. The Eagles responded with three straight touchdowns. An interception by rookie linebacker Omar Gaither set up a Jeff Garcia to L.J. Smith touchdown. With Washington in the Eagles' red zone, safety Michael Lewis reeled in a tipped pass and returned it for a touchdown. Finally, Donte' Stallworth recorded a touchdown reception after a drive which featured a 60-yard catch and run by Reggie Brown. Field goals by Suisham just before and just after halftime allowed the Redskins to linger. A 34-yard touchdown pass from Jason Campbell to Antwaan Randle El made it a 21-16 game as the fourth quarter began. The Eagles offense sputtered throughout the second half, and the Redskins drove it to the Eagles 3-yard line. However, a clutch sack by safety Brian Dawkins forced Washington to settle for a field goal. Then the Philadelphia offense made sure the Redskins didn't get the ball back by driving down the field and running out the clock.  The resurgent Garcia had a pair of touchdown passes and the 7-6 Eagles remained very much alive in the playoff chase.
