Johnny Fisher will make his promotional debut for Zuffa Boxing against Michael Pirotton this weekend.
'The Romford Bull' was a shock addition to the new promotional stable fronted by Dana White earlier this summer, when he opted to follow in the footsteps of Conor Benn by leaving Eddie Hearn's Matchroom Boxing.
Now, the hugely-popular heavyweight returns to the ring. Here's everything UK fans need to know...
When is Johnny Fisher vs Michael Pirotton?
Fisher (14-1, 12 KOs) will fight Pirotton (12-2, 6 KOs) on Saturday, Sept. 26, at the Copper Box Arena in London as the headliner of the Zuffa Boxing 11 event.
How to watch Johnny Fisher vs. Michael Pirotton in the UK
The heavyweight fight will be broadcast by Sky Sports+ from 7 p.m. BST and Sky Sports Main Event from 7.45 p.m. BST.
Ring-walk time
Fisher and Pirotton are expecting to walk to the ring between 9.45 p.m. BST and 10.15 p.m. BST.
What's at stake?
Predominantly, the future of Fisher as a meaningful threat to the heavyweight division. He has lost once -- a knockout to Dave Allen -- but has rebounded and is embarking on the key next chapter of his career.
He has left Hearn's Matchroom to pen a lucrative deal with Zuffa who won't want him to disappoint in his first fight under their banner.
Fisher is heavy-handed, ending 12 of his 14 victories inside the distance. He also possesses a large fanbase from Essex and beyond, and a father who has gained fame on social media. Only his punch power will help him in the ring, though, on a night where he will come under pressure to justify the attention.
"You want to get the knockout, you want to get the stoppage, but I've always said from the beginning of my career, I've got to win by whatever cost -- the win is the most important thing," Fisher said.
