Hoping to rebound from their tough road loss to the Patriots, the Ravens went home for a Week 5 AFC North duel with the Cincinnati Bengals.  The winner would take the lead in the division after five weeks. After a scoreless first quarter, Baltimore's defense went to work in the second quarter with safety Ed Reed returning an interception 52 yards for a touchdown.  The Bengals would answer with a 32-yard field goal from kicker Shayne Graham.  Near the end of the third quarter, Cincinnati would take the lead on a 28-yard touchdown run from running back Cedric Benson.  The Ravens would respond in the fourth quarter as quarterback Joe Flacco hooked up with running back Ray Rice 48-yard touchdown pass.  However, late in the game, the Bengals would deliver the final strike as quarterback Carson Palmer completed a 20-yard touchdown pass to wide receiver Andre Caldwell.  Baltimore tried to rally, but an interception from cornerback Leon Hall eliminated any chance of a comeback. Also, the defense's 40-game streak of keeping a single rusher under 100 yards was snapped.  The last time that Baltimore allowed a 100-yard rusher was Dec. 10, 2006 against the Chiefs' Larry Johnson.
