Johnny Fisher makes his Zuffa Boxing debut this weekend in London.‘The Romford Bull’ joined Dana White’s upstart promotion in July after spending the last five years competing under Eddie Hearn‘s Matchroom Boxing banner.Fisher left Hearn’s Matchroom Boxing for Zuffa earlier this yearGettyFisher’s deal with Matchroom came to an end after his fourth-round stoppage victory over Ivan Balaz last December.Matchroom entered negotiations over a renewal, but Zuffa blew them out of the water with an offer that Fisher claims was ‘six or seven times more’ than what Hearn and Co. had put on the table.His first assignment comes against Belgium’s Michael Pirotton, a rangy boxer-mover, with a 12-2 record.Pirotton is most notable for competing in the WBC Grand Prix last year, where he was eliminated in the round of 32 by heavy-handed Pole Piotr Lacz.Since then, he has won two out of his last three outings, with his eyes now firmly set on a big upset.Fisher vs Pirotton: Date and venueFisher and Pirotton lock horns on Saturday, September 26 at the Copperbox Arena in London.Fisher vs Pirotton: Start time and where to watchThe ten-round heavyweight clash is being broadcast by Sky Sports in the UK.Preliminary bouts will be streamed on Sky Sports‘ YouTube channel at 5pm BST before the action crosses over to Sky Sports Main Event for the main card from 7pm.Fisher and Pirotton are expected to make their respective ring walks at around 10pm.
