Coming off their win over the Bears, the Broncos returned home for an AFC duel with the New England Patriots on NBC's Sunday Night Football, on a snowy night in Denver. The Patriots, who entered the game with a 10-0 record, jumped out to a 14-0 lead, with quarterback Tom Brady tossing two touchdown passes &#8212; a 23-yarder to tight end Rob Gronkowski, followed in the second quarter by a 10-yarder to tight end Scott Chandler. The latter score occurred after Broncos' quarterback Brock Osweiler had a pass deflected and intercepted deep in Broncos' territory. The Broncos got on the scoreboard just before the two-minute warning, with running back Ronnie Hillman rushing for a 19-yard touchdown. The Broncos had a chance to cut into the Patriots' lead on their first possession of the second half, however, placekicker Brandon McManus missed wide-right on a 47-yard field goal attempt. Each team proceeded to trade punts on their next two offensive possessions, until Brady connected with wide receiver Brandon Bolden on a 63-yard touchdown pass at the beginning of the fourth quarter to give the Patriots a 21-7 lead. The Broncos' offense went three-and-out, and were forced to punt. However, Patriots' return specialist Chris Harper muffed the punt, which was recovered by Shaquil Barrett at the Patriots' 36-yard line, giving the Broncos new life. Four plays later, the Broncos pulled to within a one-touchdown deficit, with a 15-yard touchdown run by running back C. J. Anderson. The Broncos' defense forced a punt on the Patriots' next possession, which was aided by an offensive holding penalty on guard Tre' Jackson that nullified a 51-yard pass completion from Brady to wide receiver Keshawn Martin on a third-and-long play. The Broncos then marched down the field, but had to settle for a 21-yard field goal by McManus to pull to within 21-17 with 6:12 remaining in the fourth quarter. The two teams traded punts on their next possessions, and with 2:39 remaining and no timeouts, the Broncos forced a Patriots' punt. The Broncos marched down the field and were facing a 2nd-and-goal from the Patriots' 7-yard line, when Osweiler was sacked for an eight-yard loss. However, the sack was nullified by a defensive holding penalty on Patriots' safety Patrick Chung. On the very next play, the Broncos grabbed their first lead of the game, when Osweiler connected with wide receiver Andre Caldwell on a 4-yard touchdown with 1:15 remaining in the fourth quarter. The Patriots were not done yet, as Brady engineered a 5-play, 51-yard drive, which culminated with placekicker Stephen Gostkowski kicking a game-tying 47-yard field goal as time expired, sending the game to overtime. The Patriots won the overtime coin toss, but their offense went three-and-out. Following a Patriots' punt, the Broncos started their first overtime drive at their own 43-yard line, and three plays later, Anderson scampered down the sideline for a game-winning 48-yard touchdown run.
