Coming off their bye week, the Bengals stayed at home for a Week 9 AFC North rematch with the Baltimore Ravens.  Cincinnati would get off to a fast start in the first quarter as quarterback Carson Palmer hooked up with wide receiver Andre Caldwell on a 6-yard touchdown pass, while running back Cedric Benson got a 1-yard touchdown run.  In the second quarter, the Bengals would add onto their lead as kicker Shayne Graham nailed a 23-yard field goal.  After a scoreless third quarter, the Ravens tried to strike back in the fourth quarter with running back Ray Rice getting a 2-yard touchdown run, yet Cincinnati's defense held on for the victory. Chad Ochocinco jokingly flashed a $1 bill at a referee during the third quarter, and was subsequently fined $20,000 by the NFL. With the seasonal sweep over the Ravens for the 2nd time in 3 seasons, the Bengals improved to 6-2. Benson (34 carries, 117 yards, 1 TD) would join Jerome Bettis in 1997 as the only running backs to run for over 100 yards against the Ravens twice in the same season. This turned out to be Chris Henry's final game, as he was injured during the game and was placed on season-ending injured reserve. He was killed by injuries relating to a fall from a pick-up truck a month later.
