Romford heavyweight Johnny Fisher took matters into his own hands during his impressive crowd-pleasing, one-round demolition job on Dominik Musil at the O2 Arena.

In the quickest victory yet in his unbeaten seven-fight pro-winning streak, the big-punching and big ticket selling 23-year-old, who is promoted by Eddie Hearn’s Matchroom Boxing stable, admitted his pre-fight tactics became non-existent from the moment he landed a trademark overhand right that sent Musil down after 73 seconds.

Musil, 31, revisited the canvas after a similar shot 20 seconds later and, from the restart, soaked up a barrage of head shots while pinned to the ropes which prompted referee Marcus McDonnell to halt the scheduled six-round bout at 2.03.

Former Exeter University rugby union player Fisher fought a similarly built opponent in Michal Reissinger, also from the Czech Republic, last time out in Sheffield in August and successfully stopped him in two rounds.

“I’ve looked at Dominik Musil before,” said Harold Wood-born Fisher. “He’s very sturdy, a very durable guy so I thought it’s going to go a few rounds, I’ve got to break him down. That’s what I thought about Reissinger as well.

“But I caught him early and from there I thought I’ve got him caught so I’ll go for it and that was my animal instinct coming in. Once you’ve got someone hurt you’ve got to go in for it.”

In his only other visit to these shores last November Musil lasted four rounds with up-and-coming 25-year-old from Ladbroke Grove David Adeleye, who is managed by Frank Warren.

Fisher’s stablemate Demsey McKean, the world title-bound 32-year-old who recently moved from his native Australia to team up with trainer Tony Sims at his Matchroom Elite Boxing Gym near Romford, took two rounds to dispatch the Znojmo resident.

But Fisher, who is hoping to appear on the undercard of the Dillian Whyte-Jermaine Franklin international heavyweight clash on November 26, is his own fighter and has no desire to compare himself with other rival heavyweights.

“I know every fight is different and the circumstances different but for me I don’t try to compare myself too much to these guys,” he added.

“I just look at them to get bits of technique from them and from there I can make my own fight and own game plan up. 

“Tonight the game plan went out of the window when I caught him and I just went for him. The big looping right hand and I caught him from the back of his head. I didn’t have any second thoughts - just go for it - and I think that’s what people like to watch.

“Boxing is an entertainment business. We want to entertain people, we want to put bums on seats in these arenas and we want to fill them up. I’ve done 2,000 tickets and that’s what I want. We want boxing to keep growing. We want to go out to new audiences.

"With my fanbase and the people that are supporting me, it’s great that they’ve all come out and supported me in that way so I can only thank them enough. I’ve got to give a lot of credit to the Romford Bull Army as well!”

Romford flyweight Maiseyrose Courtney, 22, also features on the Wembley undercard, with the former six-time national champion from Repton ABC who also trains at the Matchroom Elite Boxing Gym near having opened her professional account with an excellent four-round success over experienced 23-fight Hungarian Judit Hachbold.
