1 Hitting a skid » The Eagles have lost five straight, with the last three by a total of 43 points. Last week's loss to the Cowboys was the low point in the Eagles' season. Dallas scored on a 30-yard pass to Dez Bryant on the final play of the third quarter to tie the game at 17-17. Then the Eagles allowed touchdowns on a punt return, interception return and fumble return in the fourth quarter, turning a tie into a 38-23 blowout loss. On top of that devastating sequence of events, the Eagles also lost quarterback Michael Vick to a concussion.

2 Facing Foles » With Vick likely to miss Sunday's game, the Redskins' defense will face rookie Nick Foles. The 6-foot-6 third-round pick completed 22 of 32 passes for 219 yards and a touchdown in relief vs. the Cowboys. Not bad numbers, but he also threw a pick-six and fumbled in his own end zone, which was recovered by Dallas. In a draft class that had five first-year quarterbacks open the season as starters, the big guy out of Arizona has been overlooked. But Foles has solid pocket presence and will have the Redskins' 30th-ranked pass defense to prove he could be the Eagles' quarterback of the future.

3 The real McCoy » With a rookie quarterback under center, the Eagles likely will turn to dynamic playmaking running back LeSean McCoy to carry the heavy load. He has 162 carries (eighth in NFL) for 705 rushing yards (10th). McCoy's big-play ability will be the Redskins' biggest concern. He led the NFL with 14 rushes of at least 20 yards last season and is second in the league this year with seven. But despite breaking off big runs, he has only two rushing touchdowns in 2012.

4 A turnover game » No team in the NFC has more turnovers than the Eagles, who have 21 giveaways (an average of 2.3 per game). Philadelphia also has just 10 takeaways for a conference-worst minus-11 turnover margin. Meanwhile, Washington has done a solid job taking care of the ball. Rookie quarterback Robert Griffin III has thrown just three interceptions, tied with the Patriots' Tom Brady for fewest among quarterbacks with more than 200 pass attempts. Washington has a plus-7 turnover margin (fifth in NFC).
