Tyson Fury was pictured licking blood off the neck of Deontay Wilder during the Gypsy King's brutal demolition of the American fighter.
Fury proved the bookies and experts wrong by stopping Wilder in round seven, handing the American his first loss - as the British fighter went on to become world champion for the second time.
Wilder's corner threw the towel in after a sustained battering by Fury, who could now look to fight Anthony Joshua in a box office Battle of Britain after bagging the WBC belt.
Fury was captured licking Wilder's blood off his neck as the brutal fight drew towards its conclusion Some viewers were shocked, but others claimed it just showed how fired up Fury was.
The Gypsy King was certain ahead of the fight that he wouldn't let the judges stop him from winning the rematch, after a controversial fight in the first fight in December 2018, and he stuck to his word.
The 31-year-old put on one of the greatest performances in heavyweight history and forced his corner to throw in the towel in seventh round, after twice putting Wilder on the floor.

Mike Tyson bit a guy's ear off and Fury licking the blood off Wilder is still the worst thing I've ever seen in a boxing match.

Fury told TALKsport that Las Vegas 'felt like Manchester' as thousands of British fans made the trip to Vegas. He also said he was in the 'prime of his life', and that he wasn't thinking about his next fight just yet.
"We've got to take one fight at a time. Deontay Wilder has a rematch clause. He might trigger it. We'll see. I'm going to have a slice of pizza and a glass of water."
Fury said he would take 'centre ring' ahead of the fight, and changed trainer to change his style, and he looked to stick to his word straight from the opening bell and was the aggressor early in the first round.
Wilder was soon countering and landed the first proper shot of the fight but it remained Fury on the front foot for most of the opening salvo and he certainly dominated the first three minutes.
The American did land a good right hand shot in the opening minute of the second round but still Fury came forward, throwing jabs, and looked to be the aggressor.
Both men landed good shots at the end of the round but it was Fury who landed the better ones, with the Brit landing a good combination right on the bell at the end of the second.
Fury landed a great shot in the first 40 seconds of the third and it bent Wilder at the knee momentarily before the champ embraced his challenger.
Suddenly a left right combination felled Wilder in the final 30 seconds of the first round and he hit the mat for one of the first times in his career to take an eight count, and the American went down again but the referee called it a slip.
Wilder came out swinging in the fourth round but it was even more erratic than his usual shots and his momentum took him to the canvas for a third time, but once again it was a slip.
There was no doubt that the home fighter was trying to lean in with his head during the clutches in an attempt to open up the cut Fury picked up during his previous fight, against Otto Wallin.
The fifth opened with Fury landing another right hand shot and once again hurting his opponent and the 34-year-old was left on his arse with an excellent left hand with just a minute and a half to go.
Fury again backed up his opponent who looked rocked and groggy and was just trying to survive, barely throwing much back but the Brit then had a point deducted for leading with his elbow.
Once again the champ was hurt at the beginning of the sixth and he was in full survival mode, leaning on the ropes, and only throwing counter shots and grabbing the dominant man.
The threat of the Bronze Bomber was still evident as he attempted a big right hand counter and only just missed but in defence he looked knackered as he stumbled back onto the ropes.
In the seventh Fury once again dominated and forced Wilder back onto the ropes and finally, after another brilliant combination, the American's corner threw in the towel to end the fight.
What a night - could this line up a massive battle of Britain with Anthony Joshua?
