Coming off their dominating win over the previously unbeaten Packers, the Broncos traveled to Lucas Oil Stadium to face the Indianapolis Colts. A 7-yard touchdown run by running back Frank Gore in the first quarter, followed in the second quarter by a 43-yard field goal by placekicker Adam Vinatieri and a 3-yard touchdown pass from quarterback Andrew Luck to tight end Jack Doyle gave the Colts a 17-0 lead. The latter scoring play occurred after Broncos' quarterback Peyton Manning was intercepted by Colts' safety Mike Adams. The Broncos got on the scoreboard in the closing seconds of the first half, with return specialist Omar Bolden returning a punt 83 yards for a touchdown. The Broncos narrowed the gap on their initial possession of the second half, with Manning throwing a 64-yard touchdown pass to wide receiver Emmanuel Sanders, then tied the game, with a 29-yard field goal by placekicker Brandon McManus. The Colts re-claimed the lead early in the fourth quarter, with an 8-yard touchdown pass from Luck to running back Ahmad Bradshaw. The Broncos responded, with a 1-yard touchdown pass from Manning to tight end Owen Daniels, in what would the final regular-season touchdown pass of Manning's career. Another field goal by Vinatieri &#8212; from 55 yards out, gave the Colts a 27-24 lead with 6:18 remaining in the game. On the Broncos' first play of their next possession, Manning was intercepted by Colts' cornerback Darius Butler. The Colts' offense forced the Broncos to use all of their timeouts, and with 28 seconds remaining, Vinatieri kicked a 23-yard field goal. However, the Colts decided not to take the points due to a defensive holding penalty on Broncos' linebacker Danny Trevathan, which enabled Luck to end the game on a quarterback kneel.
