LAS VEGAS — After three fights featuring nine combined knockdowns and many unforgettable moments, Tyson Fury finally ended his epic heavyweight rivalry with Deontay Wilder with one last valedictory punch.

Fury got up from two fourth-round knockdowns and stopped Wilder with a devastating right hand in the 11th round Sunday (PH time), retaining his WBC title in a thrilling conclusion to a superlative boxing trilogy.

Fury (31-0-1, 22 KOs) finished Wilder for the second straight time in their three bouts, but only after a back-and-forth evening featuring five combined knockdowns and several apparent moments of imminent defeat for both men. Wilder ultimately ended up facedown on the canvas at 1:10 of the 11th round after a chopping right hand fired from high in the air by the 6-foot-9 Fury.

“It was a great fight,” said Fury, the sport’s lineal heavyweight champion and a former unified world champ. “It was worthy of any trilogy in the history of the sport. He’s a top fighter, and he gave me a real (test) tonight.”

Wilder was knocked down in the third round and appeared to be on his way out, but he improbably rallied to knock down Fury twice in the final minutes of the fourth. The British champion was profoundly shaken, but he also gathered himself and fought on.

Wilder (42-2-1) absorbed enormous punishment and appeared to be physically drained for much of the bout, but the veteran American champ showed his toughness while still throwing power shots on weary legs.

Fury knocked down Wilder again with a concussive right hand midway through the 10th, but Wilder stunned Fury in the final seconds of the round. Fury persevered — and after the referee jumped in to wave it off in the 11th, Fury climbed onto the ropes in weary celebration before a frenzied crowd of 15,820 at T-Mobile Arena on the south end of the Las Vegas Strip.
