Manchester - Tokyo 2020 Olympic bronze medalist and heavyweight contender Frazer Clarke took the sixth knockout victory of his unbeaten eight fight professional career against an experienced opponent in Dave Allen.

The fight was an ugly heavyweight brawl between two men with serious KO power in both hands for the 18 minutes it lasted, with both men willing to take a few hits to give a few back, creating explosive action from the very first round.

Clarke was dominant with his steady jab and superior size and reach, but Allen remained stubbornly frustrating and hungry to stretch the fight out to the later rounds where Clarke might have tired. 

Clarke had serious success to the body but did also land some blows below the belt that forced the referee to take two points away from him in what ended up the final round. 

Allen however retired from the fight due to the damage inflicted on him by Clarke. There were conflicting details regarding the exact injury, with some observers pointing to Allen's jaw and other stating that he suffered a busted eardrum.

Clarke was satisfied with the win.

"Not vintage again but if you're going to learn on the job, let me tell you Dave Allen is the man to do it with," said Clarke afterwards. My feet were a bit lackluster, but there was some good stuff in there as well. He's a tough man, like I knew he would be.

"I tried my variations. It didn't backfire on me. Listen, it's a fighting game and I'm a clean fighter. If it strayed low and hit the belt, then I apologise to Dave right now, it was never intentional.

"I felt a few of them were good shots and I felt like him being an experienced pro with an experienced corner, they tried to manipulate the referee. They've followed the media and what's been going on these past weeks. Fair play to them, they tried using it to their advantage."
