The Broncos, making their first visit to New Orleans since 2004, jumped out to a 10-0 lead. First, quarterback Trevor Siemian connected with wide receiver Jordan Taylor on a 14-yard touchdown pass. The touchdown was initially ruled as an incomplete pass, but overturned by a replay challenge. Following an interception of Saints' quarterback Drew Brees by cornerback Darian Stewart, placekicker Brandon McManus added a 50-yard field goal early in the second quarter. The Broncos were attempting to add to their lead just before halftime, however Siemian was intercepted by cornerback Sterling Moore, and the Saints quickly advanced 50 yards in only 29 seconds, culminating in a 30-yard field goal by placekicker Will Lutz. Early in the third quarter, the Saints tied the game, with Brees connecting with wide receiver Willie Snead on a 3-yard touchdown pass. On the Broncos' second possession of the second half, Siemian was intercepted by safety Kenny Vaccaro, and four plays later, another touchdown pass from Brees to Snead from 5 yards out gave the Saints a 17-10 lead. On the Broncos next drive, McManus missed wide left on a 42-yard field attempt early in the fourth quarter. Two plays into the Saints' next possession, Broncos' cornerback Bradley Roby forced a fumble off wide receiver Michael Thomas, which was recovered by Stewart at the Saints' 27-yard line. Seven plays later, the Broncos tied the game, with a 2-yard touchdown pass from Siemian to wide receiver Demaryius Thomas. After forcing the Saints to go three-and-out, the Broncos drove down the field, but had to settle on a 28-yard field goal by McManus. The Broncos' defense forced another fumble deep in Saints' territory, but had to settle on a 37-yard field goal by McManus with 2:50 remaining in the game, while forcing the Saints to burn the last two of their three team timeouts. The Saints then drove 75 yards in only six plays, culminating in Brees throwing a 32-yard touchdown pass to wide receiver Brandin Cooks to tie the game at 23-23 with 1:30 remaining in the game. However, Lutz's extra point attempt was blocked by Justin Simmons, and Will Parks scooped up the football and ran to the end zone for a defensive two-point conversion. The Saints claimed that Parks may have stepped out of bounds, but the initial ruling on the field was upheld after an instant replay review. The Saints' onside kick attempt was unsuccessful, sealing the win for the Broncos. Darian Stewart became the Broncos' first defensive player since Deltha O'Neal in 2001 to record three takeaways in one game.
