Could Sam Darnold be the next Joe Namath or Mark Sanchez off the field?

Surging New York Jets quarterback Darnold celebrated his team’s Sunday afternoon routing of the Raiders long into the night — but he may have taken on a little too much “jet fuel,” sources tell Page Six.

We’re told that Bounce Sporting Club in the Flatiron District hosted Darnold and his teammates after they walloped the Oakland Raiders 34-3 at MetLife Stadium.

“They were celebrating like they’d just won the Super Bowl,” said a spy on the scene. “Sam Darnold was wasted, hooking up with some girl. The other guys on the team had to [look after] him.”

“[There was] a limo driving him and the players around all night,” added the source.

Meanwhile, an insider told us, “His team protects him — that’s the way they are on the field, and off it. He’s the franchise.”

We’re told Darnold ducked out at about 12:30 a.m. Monday, but the rest of the team partied on.

Darnold had been romantically linked to a fellow student at USC, which he left to play for the Jets in 2018. Heavy.com reports that it’s unclear if they’re still together: “Darnold has not posted a photo with [her] since 2017 when the couple attended a wedding together.” Another insider told Page Six that they don’t believe the rising star has a girlfriend.

Jets Jamal Adams, Trumaine Johnson, Darryl Roberts, Brian Poole and Marcus Maye were among the revelers. We’re told they were also having an early celebration for Roberts’ birthday — he turns 29 on Tuesday.

“Bounce is a second home to a lot of the guys,” said an insider.

It should be noted that the team doesn’t have any rules against its players drinking.

The team won their third straight game on Sunday, marking the squad’s first three-game winning streak since 2017. Darnold threw for two touchdowns and ran for another.

A rep for the Jets declined to comment.
