In the first quarter the Titans took a sudden lead with WR Marc Mariani returning a punt 87&#160;yards for a touchdown. The Redskins replied with QB Donovan McNabb completing a 5-yard TD pass to WR Santana Moss, followed in the second quarter by kicker Graham Gano nailing a 19-yard field goal. The Titans got the lead back after kicker Rob Bironas made a 25 and a 32-yard field goal. However, the Redskins replied with Gano hitting a 40-yard field goal. The Titans scored with Bironas nailing a 40-yard field goal, but the Redskins replied again with Gano making a 42-yard field goal. The decision was made at Overtime after Gano successfully hit a 48-yard field goal to give the Titans the loss, settling the records for both teams at 5-5 and the Titans' 14-game winning streak against NFC Opponents was snapped. During the game, Vince Young suffered a torn flexor tendon in his right thumb.  He was replaced by Rusty Smith.  Young was held out of the game after he was prepared to reenter.

Fisher then declared that Smith would become the Titans' starting quarterback.
