Coming off their dominating road win over the Raiders, the Rams played their last home game of the year as they took on the Washington Redskins.  In the first quarter, the Redskins struck first with RB T. J. Duckett getting a 5-yard TD run for the only score of the period.  In the second quarter, St. Louis took the lead with QB Marc Bulger completing a 10-yard TD pass to WR Isaac Bruce and a 27-yard TD pass to rookie TE Dominique Byrd.  However, Washington responded with RB Ladell Betts getting a 6-yard TD run and QB Jason Campbell completing a 9-yard TD pass to TE Chris Cooley.  In the third quarter, the Redskins increased their lead with Betts getting a 7-yard TD run.  The Rams responded with Bulger completing a 64-yard TD pass to RB Stephen Jackson and a 10-yard TD pass to RB Stephen Davis.  In the fourth quarter, St. Louis took the lead with kicker Jeff Wilkins getting a 21-yard field goal, yet Washington managed to tie the game with kicker Shaun Suisham getting a 52-yard field goal.  In overtime, the Rams won with Jackson getting a 21-yard TD run.  With the win, St. Louis improved to 7-8. However, because the New York Giants won a Week 17 match-up against the Washington Redskins, it ended any chance for the Rams to get into the playoffs.
