On the Broncos' second possession of the game, quarterback Trevor Siemian connecting on a 22-yard touchdown pass to tight end A. J. Derby. After forcing a Raiders' punt, Isaiah McKenzie returned a punt 64 yards to the Raiders' 15-yard line, but it was nullified by an illegal block penalty on Kasim Edebali. The Broncos marched down the field from their own 11-yard line to the Raiders' 6-yard line, but could not take advantage of the red zone opportunity, settling instead for a 28-yard field goal by placekicker Brandon McManus. After each team exchanged punts on their next two possessions, the Raiders got on the scoreboard late in the second quarter, with a 5-play, 99-yard drive, culminating in a 16-yard touchdown pass from quarterback Derek Carr to wide receiver Johnny Holton. McManus added a pair of field goals &#8212; from 36 and 46 yards out &#8212; to increase the Broncos' lead to 16-7. Late in the third quarter, Carr left the game due to a back injury, and backup quarterback EJ Manuel took over. The Broncos failed to take advantage of yet another red zone opportunity early in the fourth quarter, as a 29-yard field goal attempt by McManus hit the left upright. Following another exchange of punts, the Raiders narrowed the Broncos' lead to 16-10, with a 38-yard field goal by placekicker Giorgio Tavecchio with 5:27 left in the game. After the Broncos went three-and-out, the Raiders had one last possession with 4:16 remaining in the game, and reached the Broncos' 36-yard line at the 2-minute warning. After a false start penalty pushed the Raiders back five yards, a long pass attempt from Manuel intended for wide receiver Amari Cooper was intercepted by safety Justin Simmons, sealing the win for the Broncos. The Broncos' defense limited Marshawn Lynch to just 20 yards rushing on nine attempts.
