The two teams exchanged field goals in the first quarter, with a 48-yarder by Colts' placekicker Adam Vinatieri and a 23-yarder by Broncos' placekicker Brandon McManus. A 4-yard touchdown run by running back C. J. Anderson gave the Broncos the lead early in the second quarter. Vinatieri and McManus once again exchanged field goals late in the first half, with a 52-yarder by Vinatieri and a 43-yarder by McManus just before halftime. The Colts took the initial possession of the second half and tied the game at 13-13 midway through the third quarter, with running back Robert Turbin rushing for a 5-yard touchdown. However, the Broncos took the lead for good later in the third quarter, with a 33-yard field goal by McManus. On the Colts' next possession, quarterback Andrew Luck was intercepted by Broncos' cornerback Aqib Talib, who scampered 46 yards down the sideline for a touchdown to give the Broncos a 23-13 lead early in the fourth quarter. Following an exchange of punts, the Colts narrowed the Broncos' lead, with Luck connecting with running back Frank Gore on a 7-yard touchdown pass with four minutes remaining in the game. The Broncos then increased their lead to 26-20 on the first play after the two-minute warning, with McManus' fourth field goal of the game&#8212;a 35-yarder&#8212;and in the process, forced the Colts to burn all three of their timeouts. The Colts had one last offensive possession, hoping for a game-winning drive, however, on the very first play from scrimmage, Luck was strip-sacked by Broncos' linebacker Von Miller, and linebacker Shane Ray returned the fumble 15 yards for a game-clinching touchdown (with a two-point conversion pass from quarterback Trevor Siemian to wide receiver Demaryius Thomas). Demaryius Thomas passed Ed McCaffrey for fourth-place on the Broncos' all-time career receptions list&#8212;Thomas only trails Lionel Taylor, Shannon Sharpe and Rod Smith.
