A furious Julian Edelman went off on the Patriots Sunday after his former team suffered an embarrassing, last-minute loss to the Raiders in Las Vegas.

Edelman, who was sitting in a private suite at Allegiant Stadium, dropped an F-bomb while witnessing New England’s stunning collapse following a failed lateral throw from Patriots wide receiver Jakobi Meyers.

“What the f–k are we doing?” the former Patriots wideout yelled in a clip shared on Twitter. “What are we doing?”

Warning: Explicit language

Edelman, a former Super Bowl MVP who won three championships with the Patriots, then ripped off his Red Sox cap and furiously tossed it nearby.

With the game tied at 24-24 in the fourth quarter and only three seconds remaining, Patriots running back Rhamondre Stevenson tossed a lateral pass to Meyers, who then attempted a second lateral throw to quarterback Mac Jones — but it was picked off by Raiders defensive end Chandler Jones for a game-winning touchdown.

Meyers expressed remorse over the turnover in the 30-24 loss, which might’ve cost the Patriots a playoff spot.

“I was just trying to do too much, trying to be a hero, I guess,” Meyers said postgame. “I didn’t see the dude back there, trying to throw the ball. Like I said, I was just doing too much. I should have just went down with the ball.”

The unbelievable sequence of events also cost Patriots coach Bill Belichick a chance at defeating his former longtime offensive coordinator, Raiders coach Josh McDaniels.

“We talk about situational football,” Belichick said. “We talk about it every week, but we obviously have to do a better job playing situational football and not making critical mistakes.”

Meanwhile, McDaniels called the wild finish “probably the most insane ending I’ve ever been a part of.”

“We’ll take it. We’ll take it for sure,” he continued.
