Fisher vs Pirotton: Johnny Fisher wins by majority decision in first fight for Zuffa Boxing

The 7,500-capacity Copper Box was far from full, with the upper tier closed and empty seats scattered around the arena.

But Fisher’s “Bosh Army” did its best to fill in the gaps with noise, giving the “Romford Bull” a raucous reception.

Alongside his social media star father, “Big John,” Fisher has built a loyal following through an unusually unfiltered insight into family life, training camps and the couple’s well-documented enthusiasm for Chinese takeout.

Fisher started with intent, swinging heavy hooks and making Pirotton’s eyes red in the first round.

The little-known Belgian was unfazed by the local support or pressure from Fisher, but his eye was cut out within a second.

“I can see, don’t stop the fight,” Pirotton told the referee before a doctor examined him in the fourth quarter.

Allowed to continue, he fired, but Fisher responded with a burst to the head and body.

Blood stained Pirotton’s white shorts, but he recovered in the fifth – his best round – as Fisher began to look tired and static.

Attendees included British fighters Derek Chisora, Conor Benn and Caroline Dubois, alongside WWE stars AJ Styles and LA Knight.

WWE is owned by the American sports and entertainment group TKO, which is also behind Zuffa Boxing.

The doctor examined Pirotton again before the seventh but allowed the fight to continue.

Neither man offered much in the closing stages until a short right hand from Fisher sent Pirotton reeling in the 10th.

For a moment, a 13th stoppage victory appeared within his reach, but Fisher could not find the final burst as Pirotton slipped to his third defeat in 15 fights.
