Answer based on context:

Coming off a road win over the Cowboys, the Redskins traveled to Lincoln Financial Field for a Week 5 NFC East duel with the Philadelphia Eagles. In the first quarter, the Redskins trailed early as RB Brian Westbrook scored on a 9-yard TD run and the Eagles DeSean Jackson returned a punt 68 yards for a touchdown.  In the second quarter, Washington responded with Shaun Suisham kicking field goals of 41, 48, and 50 yards.  In the third quarter, the Redskins took the lead on a trick play as WR Antwaan Randle El threw an 18-yard TD pass to TE Chris Cooley. In the fourth quarter, the Redskins increased their lead when Clinton Portis scored on a 4-yard TD run.  Afterwards, the Eagles were unable to rally, only managing a 23-yard field goal by kicker David Akers.
