Fury, who beat Wladimir Klitschko in November, was in Brooklyn to watch WBC champion Wilder beat the Polish fighter — who was still sprawled out on the canvas — when Fury hopped into the ring.
And after Wilder won Saturday's fight with a devastating ninth round knockout, the British loudmouth jumped through the ropes, slammed down his jacket and stormed around the ring.
With Mike Tyson and Lennox Lewis looking on, Wilder and Fury then squared up with the Brit taking the microphone and shouting, "There's only one Tyson Fury. What have you got to say about that Deontay?"
After getting in the winner's face, Fury crowed, "Any time! Any place! Anywhere. I'll fight you in your back garden.
"Like I did Klitschko, I'll beat you, ya bum, You're a bum."

Security stepped in to separate the two fighters and Wilder hit back at Fury, saying: "You can run around like you're a preacher all you want but you step in the ring, I promise you I will baptize you.
"This is an act. You're not a real fighter. This is an act. I don't play this. You should be an actor. This ain't WWE.
"I would love to fight him next. Unfortunately I have other mandatories due. Make the date Tyson, I promise you."
Fury dramatically gestured toward the crowd as he was booed by the fans and then escorted out of the Barclays Center by security.
A fight between Wilder and Fury may not have been signed yet — but you have to admit there is finally some interest being hyped in the heavyweight division.
