The Raiders next traveled to Denver for their first division game of the year. Once again, the Raider offense struggled, not managing any points until the second quarter. The Denver offense looked good on its second possession of the game, moving 88 yards on seven plays and opening the scoring as Trevor Siemian hit A. J. Derby on a 22-yard pass and catch for a touchdown. Following a quick Raider possession and trailing 7-0, the Raider defense was able to limit Denver to a Brandon McManus 28-yard field goal, stopping the Broncos on the 79-yard drive. Finally, with 5:59 seconds remaining in the second quarter, the Raiders offense came alive. Beginning on their own one-yard line, the Raiders quickly moved out to their 36-yard line before Derek Carr hit Johnny Holton on a bomb for a 64-yard touchdown pass which brought the score to 10-7. The half ended with both offenses managing nothing further. The Raiders began the second half with the ball, but could not manage a first down again, punting the ball back to the Broncos. Denver capitalized, driving 55 yards before settling for another McManus field goal to move the score to 13-7. A three-and-out by the Raiders on their ensuing possession led to another McManus field goal which extended the Bronco lead to 16-7. Looking to close the gap, the Raiders again failed to manage a first down and attempted a fake punt from inside their own 35-yard line where punter Marquette King attempted to run for the first down, but was instead dropped for a three-yard loss. The Broncos failed to capitalize as McManus missed a 29-yard field goal. Derek Carr was sacked on the first play of the Raiders next possession and had to leave the game with a back injury. Backup quarterback EJ Manuel could not get a first down as the Raiders were forced to punt again with less than three minutes remaining in the third quarter. Neither team managed any points on their first possessors of the fourth quarter. With 8:30 remaining in the game, the Raiders went no huddle and EJ Manuel led the team down the field with five consecutive completions. However, the drive stalled and the Raiders were forced to settled for a Giorgio Tavecchio 38-yard field goal with 5:27 left in the game. The Raider defense forced Denver to punt and Manuel took over with 4:16 left in the game. Completing three of four passes, the Raiders moved to the Denver 41-yard line. However, Manuel's next pass was intercepted by the Broncos at the Denver eight-yard line with 1:46 remaining in the game to end the Raider comeback hopes. For the second consecutive week, the Raider offense struggled managing only 24 yards rushing while only putting up 249 yard through the air. The Raider defense played well limiting the Broncos to only 298 total yards. The following day, it was announced that Carr had broken a bone in his back (transverse process fracture) and would miss two to six weeks.
