Joseph Parker crashed to his second career defeat after losing to Dillian Whyte in a gruelling 12-round war.
The Kiwi heavyweight rallied from getting knocked down twice to put Whyte down in the 12th round, but it was too little too late as the brave Brit hung on to claim a career-best victory.
Here's how the media and fans from around the world reacted to the thrilling heavyweight contest:
'10 more seconds and Whyte was finished'
The bout lived up to the hype, with some calling it a contender for fight of the year.
Fans slam 'biased' Sky commentary
As Chris Rattue wrote in his report: "Parker copped repeated criticism from the British Sky commentators from the middle of the round, the pundits accusing him of being "one paced", looking "lethargic", "not giving everything he's got".
"They even accused him of "feeling sorry for himself" and being too much "Mr Nice Guy"."
But some fans weren't having Sky's "biased" commentary.

Dillian Whyte survives late onslaught from Joseph Parker to stake his claim for world title shot - by Luke Brown of the Independent
"This was meant to be the fight that ascertained once and for all who deserves their place at the front of the heavyweight queue, the fight that ordained the opponent in waiting for the likes of Anthony Joshua and Deontay Wilder. And yet after a wild night in front of a sell-out queue at The O2, the picture appears to be more muddled than ever. Dillian Whyte picked himself up off the canvas to beat Joseph Parker -- but only just."
'What a sad watch. Whole thing was sad.'
