WBC champion Tyson Fury defeated Dillian Whyte with a stunning one-punch stoppage in the sixth round with a vicious right uppercut.
The challenger got to his feet but the fight was halted after he staggered into the referee within the count.
After his victory, Fury, took the microphone and treated fans to his own rendition of ‘American Pie’ in the ring.
Before the fight, Fury insisted that this would be his last and during the post-fight interview, Tyson said “This might be the final curtain for the Gypsy King.”
He added later: “I’ve spent a lot of time on the road. I’ve been away for a long time. I fulfilled everything I’ve ever wanted to fulfil.
“I will retire as only the second heavyweight in history, after Rocky Marciano, to retire undefeated. I was unbeatable at this game.”
“I promised my wife that would be it after the [Deontay] Wilder fight,” he added. “But I got offered a fight at Wembley and I owed it to the fans. What a way to go out.”
Fury is unbeaten in 33 bouts, while Whyte – suffering his third loss in 31 fights – fell short on his first attempt at a world title.
If the 33-year-old does decide to hang up his gloves, he will miss out on an opportunity to fight for the undisputed crown – a fight which could potentially be staged later this year – and a chance to cement his status as Britain’s greatest ever heavyweight.
A rematch with rival Joshua, should he lose against Usyk, is easy to sell and one which could capture the imagination of boxing fans.
