The Broncos returned to INVESCO Field at Mile High in a highly anticipated showdown with the Indianapolis Colts and their high-powered offense led by Peyton Manning. Going into the game, Indianapolis was one of just two undefeated teams in the NFL (along with the Chicago Bears) with a 6-0 record. Unlike the other games the Broncos played up to this point, this game turned into a shootout in the second half, with Peyton Manning playing a nearly flawless game. By the end of the first half, the Broncos had already scored 14 points (3 below their season high up to this point). The Colts scored first, with a 42-yard field goal by Adam Vinatieri in the first quarter. The Broncos took a quick lead in the second quarter with two consecutive 80-yard drives for touchdowns; one a 1-yard run by Jake Plummer, his first of the season on running, and the second a 15-yard pass to Javon Walker. The Broncos went into the half leading 14-6 after a 32-yard field goal by Vinatieri. The Colts responded with a 12-yard touchdown catch by Reggie Wayne in the third quarter. The only turnover of the game came on a Jake Plummer fumble on the next drive by the Broncos, leading to another easy touchdown pass to Wayne, putting the Colts ahead 17-14. A touchdown run by Mike Bell, who was substituting for the slightly injured Tatum Bell, put the Broncos on top again. Each team responded with a touchdown in the fourth quarter, with Bell running for another touchdown and Wayne hauling in another touchdown pass (followed by a 2-point conversion pass that was also caught by Wayne). The 37-yard field goal by Vinatieri with 2 seconds left won the game for the Colts, breaking the tie and allowing them to remain undefeated. He had another 48-yarder earlier in the quarter, while Jason Elam had previously tied the game on a 49-yard field goal. The game proved to be good for both offenses; while Denver allowed the most points they had all season, they also scored more points than they had all season. Peyton Manning tore up the Broncos defense, throwing for 345 yards (138 by Wayne) on 32/39 passing, and 3 touchdowns (all to Wayne). Denver's powerful run attack (currently third in the league behind the Atlanta Falcons and San Diego Chargers) gained 227 yards against the league-worst Colts run defense (including 136 by rookie Mike Bell), but it simply wasn't enough to counter the Colts' powerful offense (which also ran for 93 yards, all by rookie Joseph Addai, a career-high). Denver again moved into a first place tie in the AFC West with the San Diego Chargers as they won their game against the St. Louis Rams.
