The Raiders traveled to Tampa Bay looking to improve to 6-2 overall and 5-0 on the road on the season. Tampa scored on a Roberto Aguayo 41-yard field goal and Jameis Winston threw a 19-yard touchdown pass to put the Buccaneers up 10-0 early in the second quarter. The Raiders started slow, managing only a Sebastian Janikowski field goal in the first half and the Bucs led 10-3 at the half. The Raiders offense came alive in the second half as Derek Carr hit offensive lineman Donald Penn on a tackle eligible play from the 1-yard line for his first touchdown pass of the game, to tie the game at 10. On the next Raider possession, Carr hit Amari Cooper on a 34-yard touchdown pass to give the Raiders their first lead of the game. However, Tampa Bay answered soon thereafter, taking the lead on Cameron Brate touchdown reception and a Jacquizz Rodgers touchdown run to move ahead 24-17 early in the fourth quarter. Carr threw his third touchdown of the game, this time to tight end Mychal Rivera with 1:38 remaining in the game. With the game tied and the clock running out, the Bucs punted the ball back to the Raiders with 58 seconds remaining. The Raiders drove to field goal position, but Janikowski missed a 50-yard field goal wide left as time expired to force overtime. On the first possession of overtime, the Raiders again moved into scoring position, but due to penalties were forced to settle for a 52-yard field goal attempt which Janikowski missed wide right. The Raider defense held the Buccaneers to consecutive three and out series and the Raiders took over with 3:21 left in overtime. Carr led the Raiders to the Tampa Bay 41, and coach Jack Del Rio chose to go for it on fourth down. Carr hit Seth Roberts for the first down and he broke tackles as he scampered 41 yards for the game-winning touchdown. Carr threw for a franchise record 513 yards on 40-59 passing with four touchdowns. The Raiders won despite setting an NFL record for penalties in a game, with 23 total penalties. The win kept the Raiders in a first place tie with Denver at 6-2. The Raiders moved to 5-0 on the road for the first time since 1977.
