Coming off their Sunday Night win over the Lions, the Broncos returned home for an interconference game vs. the Minnesota Vikings, the Broncos' only home game within a six-week span. The Broncos jumped out to a 13-0 lead, consisting of a 33-yard field goal by place kicker Brandon McManus, followed in the second quarter by a 72-yard touchdown run by running back Ronnie Hillman and another field goal by McManus &#8212; from 47 yards out. The Vikings got on the scoreboard just after the two-minute warning, with a 38-yard field goal by placekicker Blair Walsh. The Broncos were attempting to add to their lead on the Vikings' side of the field, however, quarterback Peyton Manning was intercepted by Vikings' linebacker Anthony Barr, who returned the football to the Broncos' 27-yard line. Two plays later, the Vikings narrowed the Broncos' lead, with quarterback Teddy Bridgewater finding wide receiver Mike Wallace alone in the end zone for a 4-yard touchdown just before halftime. The Broncos took the opening possession of the second half, and added to their lead, with a 1-yard touchdown pass from Manning to tight end Owen Daniels on a 4th-and-goal. Each team alternated punts on the next four possessions, until Vikings' running back Adrian Peterson went untouched for a 48-yard touchdown on a 4th-and-1, with 10:09 remaining in the fourth quarter. Two plays into the Broncos' next possession, Manning was intercepted by safety Harrison Smith, and nine plays later, the Vikings pulled even at 20-20, with a 33-yard field goal by Walsh. The Broncos took a 23-20 lead two plays after the two-minute warning, with a 39-yard field goal by McManus. The Vikings had one last possession with 1:51 remaining in the game, however, on the sixth play of their final drive, Broncos' safety T. J. Ward forced a fumble off Bridgewater at the Vikings' 42-yard line, and linebacker Von Miller recovered the game-clinching fumble.
