The Broncos kicked off their 2014 season against the Indianapolis Colts on NBC's Sunday Night Football. A 21-yard field goal by Broncos' placekicker Brandon McManus was the only scoring play of the first quarter. In the second quarter, the Broncos increased their lead to 24-0, with quarterback Peyton Manning throwing three touchdown passes to tight end Julius Thomas &#8212; a 3-yarder, a 35-yarder and a 5-yarder. The Colts got on the scoreboard just before halftime, with quarterback Andrew Luck rushing for a 9-yard touchdown. On the Colts' first offensive possession of the second half, the Broncos' defense made a goal-line stand, as linebacker Brandon Marshall snuffed out Luck's attempt of a quarterback sneak on 4th-and-goal. Colts' placekicker Adam Vinatieri added a 25-yard field goal later in the third quarter. The Broncos increased their lead to 31-10 with 9:54 remaining in the fourth quarter, with running back Montee Ball rushing for a 3-yard touchdown. The Colts responded on their next possession, with Luck connecting on a 41-yard touchdown pass to wide receiver Dwayne Allen to pull within 31-17 midway through the fourth quarter. The Colts subsequently recovered an onside kick, however, eight plays later, Luck was intercepted by Broncos' safety Rahim Moore deep in Broncos' territory. The Broncos' offense forced the Colts to burn two of their three team timeouts on their next possession, but went three-and-out. The Colts pulled to within 31-24 with 3:32 remaining in the game, with Luck throwing a 9-yard touchdown pass to wide receiver Hakeem Nicks. The Broncos' offense subsequently went three-and-out on their next possession, and were forced to punt with three minutes left in the game. The Colts attempted a rally, however, Broncos' cornerback Bradley Roby broke up a 4th-down pass from Luck that was intended for wide receiver Reggie Wayne on the first play after the two-minute warning. The Broncos' offense subsequently ran out the clock.
