PROBLEM: Passage: Coming off of their dominant home win over the Steelers, the Ravens flew to Paul Brown Stadium for an AFC North rematch with the Cincinnati Bengals, trying to win the division and a playoff berth on this Thursday Night fight.  After a scoreless first quarter, the Ravens trailed early as Bengals kicker Shayne Graham kicked a 23-yard and a 27-yard field goal.  In the third quarter, things went from bad to worse for Baltimore as QB Carson Palmer completed a 40-yard flea-flicker TD pass to WR T. J. Houshmandzadeh for the only score of the period.  In the fourth quarter, the Ravens valiantly tried to fight back, as QB Steve McNair completed a 36-yard TD pass to WR Derrick Mason.  However, a failed onside kick spelled Baltimore's doom.  With the loss, the Ravens fell to 9-3.
