The Broncos traveled to Gillette Stadium to play the New England Patriots during the Sunday night game on September 24. The game was a rematch of the divisional playoff game of the previous season in which the Broncos beat the Patriots and ended their record 10-game playoff winning streak.  The Broncos won 17-7, improving their record to 2-1.  The Broncos scored a 23-yard field goal (by kicker Jason Elam) and a touchdown in the second quarter (a 32-yard TD pass from QB Jake Plummer to Javon Walker). Plummer and Walker would hook up for another touchdown in the fourth quarter with an 83-yard touchdown pass. The Broncos held New England to only 50 yards on the ground, while Tatum Bell ran for 123 yards. The Patriots scored a touchdown in the fourth quarter when Tom Brady threw an 8-yard pass to Doug Gabriel. The Broncos became the first team since the 1942 Chicago Cardinals to begin their season with 11 straight quarters without allowing their opponents to score a touchdown.
