OAKLAND, Calif. — After the final seconds ticked off, Derek Carr ran straight to the Black Hole with several teammates before taking a victory lap around the Coliseum to celebrate with his fans.

If this truly is the final game ever in Oakland, the Raiders gave their fans plenty to cheer at the end of another disappointing season.

Dwayne Harris returned a punt 99 yards for a touchdown after Denver failed to down it, Oakland native Doug Martin ran for 107 yards and a score and the Raiders beat the Broncos 27-14 on Monday night in what was possibly the final NFL game ever at the Coliseum.

“It was emotional because as I was doing it, I was remembering all the memories from breaking my ankle, to fourth-quarter comeback wins, to throwing three picks in a quarter. Everything,” Carr said. “Just how loyal our fans are. I know it stings. I know it hurts that we might not play here. I don't know. I was going to make sure that if this was the last time, I wanted to say thank you in whatever way I could.”

The Raiders (4-11) are set to move to Las Vegas in 2020 and have no lease for next year. With Oakland officials having sued the team over the move, the Raiders are looking into other options for 2019, including AT&T Park in San Francisco.

A decision is expected before the Super Bowl, but many of the die-hards came out for this game knowing it could be the last NFL game ever in the stadium that opened in 1966.

“I don't want to get too sentimental tonight,” coach Jon Gruden said. “Hopefully that's not the case. That's for other people to decide. You see the love affair these fans have for the Raiders.”

While the Raiders celebrated, the Broncos (6-9) hit a low after being assured of having back-to-back seasons with losing records for the first time since 1971-72. After going 5-11 in coach Vance Joseph's first season, Denver has done little better in year two and general manager John Elway could be ready to make a change after the season.

The Broncos opened the month with playoff aspirations, but three straight losses to teams that entered the game with losing records ended those hopes and have the team searching for answers.

“The message is to keep fighting,” Joseph said. “That's what we do right now. We have one more game left and this team's fought all year.”

Shortly after Oakland native Marshawn Lynch lit the torch in honor of late owner Al Davis before the game, Harris delivered the biggest highlight with a punt return that was tied for the second-longest ever.
