Hoping to rebound from their road loss to the Giants, the Ravens went home for a Week 12 interconference duel with the Philadelphia Eagles.  Baltimore scored the first points of the game late in the second half with a 44-yard field goal by kicker Matt Stover, while rookie quarterback Joe Flacco and TE Daniel Wilcox connected on a 1-yard TD pass, set up by an interception by safety Ed Reed.  The Eagles would close out the half with safety Quintin Demps returning a kickoff 100 yards for a touchdown.  In the third quarter, the Ravens answered with rookie LB Jameel McClain blocking a punt that resulted in a safety.  In the fourth quarter, Baltimore scored additional unanswered points as Stover nailed a 42-yard field goal, Flacco completed a 53-yard TD pass to WR Mark Clayton, Reed set an NFL record with a 108-yard interception return for a touchdown, and FB Le'Ron McClain scored on a 1-yard TD run.
