Meanwhile, the Patriots first defeated the Tennessee Titans, 17–14, in one of the coldest games in NFL history, with temperatures reaching 4 °F (−15 °C). New England jumped to 14–7 lead in the first half with a touchdown pass by Brady and a touchdown run from Smith. However, quarterback Steve McNair's 11-yard touchdown pass to receiver Derrick Mason tied the game in the third period. With 4:06 remaining in the game, Patriots kicker Adam Vinatieri made a 46-yard field goal to take the lead. New England's defense later clinched a victory as they stopped the Titans from scoring on fourth down on their last drive of the game.
