Coming off their home win over the Falcons, the Rams flew to Paul Brown Stadium for a Week 14 interconference duel with the Cincinnati Bengals.  With QB Marc Bulger out with a concussion and veteran back-up QB Gus Frerotte out with a shoulder injury, rookie QB Brock Berlin got his first NFL start. In the first quarter, St. Louis trailed early as Bengals RB Rudi Johnson got a 1-yard TD run for the only score of the period.  In the second quarter, the Rams continued to trail as kicker Shayne Graham gave Cincinnati a 27-yard field goal for the only score of the period. In the third quarter, St. Louis got on the board as CB Fakhir Brown returned an interception 36&#160;yards for a touchdown, yet the Bengals responded with Graham kicking a 38-yard and a 32-yard field goal.  In the fourth quarter, the Rams tried to come back as kicker Jeff Wilkins managed to get a 50-yard field goal.  However, Cincinnati sealed the win with Graham nailing a 46-yard field goal. This would also be the 5th time this year that the Rams were held to 10 or fewer points. On a positive note, WR Torry Holt went over 1,000 receiving yards for the eighth-straight year.
