Keep an eye on the ground this week in Philly.

Gaining Ground: The Redskins have leapfrogged in both ESPN and CBS power rankings (to 6th and 4th respectively) after beating the previously undefeated Cowboys Sunday in Dallas. Santana Moss was second among receivers this week in total yards (8 catches for 145 yards) while Clinton Portis was second among running backs (121 yards on 21 carries). The Redskins defense allowed only 44 total yards rushing against Dallas, and Jason Campbell still hasn’t thrown an interception.

Not Giving Ground: Philadelphia has the third best defense in the NFL, the most sacks (17), and is ranked #1 against the run.

The Lame Ducks: If Brian Westbrook (strained right ankle) plays Sunday for Philly, the landscape of the game gets rough for Washington. Westbrook racked up 183 total yards the last time he played the ‘Skins and is a league-leader in touchdowns scored this season. Donovan McNabb is suffering from a bruised chest (supposedly more painful than a bruised ego) but is expected to start Sunday; however, rumor is his injury did affect Philly’s play calling against the Bears last week (McNabb denies this, but ESPN.com has a different take from head coach Andy Reid). Wednesday’s official injury report lists McNabb, Westbrook, and cornerback Asante Samuel at “limited participation.” Meanwhile, the return of the Foxtrot king Jason Taylor is still uncertain for the Redskins, and Stephon Heyer is listed as questionable.
