Hoping to add to an eight-game winning streak, the Broncos traveled to M&T Bank Stadium for an AFC duel with the Baltimore Ravens, where the Broncos had never won in four previous regular-season meetings. A 27-yard field goal by Broncos' placekicker Matt Prater was the only scoring play of the first quarter. The Broncos increased their lead in the second quarter, with fullback Jacob Hester rushing for a 1-yard touchdown. The Ravens were threatening to narrow the Broncos' lead just before halftime; however, Broncos' cornerback Chris Harris, Jr. stepped in front of a pass from Ravens' quarterback Joe Flacco, returning an interception 98 yards for a touchdown. The Ravens finally got on the scoreboard in the third quarter, with a 45-yard field goal by placekicker Justin Tucker. However, the Broncos added to their lead, with quarterback Peyton Manning throwing a 51-yard touchdown pass to wide receiver Eric Decker, followed by a 6-yard touchdown run from running back Knowshon Moreno to give the Broncos a commanding 31-3 lead. The Ravens finally got into the end zone early in the fourth quarter, with Flacco connecting on a 31-yard touchdown pass to tight end Dennis Pitta, but the Broncos responded with a 36-yard field goal from Prater. The Ravens added one more score, with a 61-yard touchdown pass from Flacco to Pitta, but the Broncos' lead was too much for the Ravens to overcome. This was the Broncos' first-ever regular-season win in Baltimore in five tries.
