11 former UFC fighters were in action, including Bryan Battle after his UFC firing and legend Hector Lombard. Their outings set the stage for a main event title fight featuring Rozenstruik<\/a>, who fought 23-18-1 MMA pro Rakim Cleveland.<\/p>\n Rozenstruik\u2019s shot at becoming the inaugural Dirty Boxing heavyweight king came after he debuted under the banner with a vicious one-punch knockout this past June<\/a>. And \u2018Bigi Boy\u2019 certainly picked up where he left off\u2026<\/p>\n Dirty Boxing was created by ex-UFC star and BKFC brawler Mike Perry<\/a>. The format permits elbows and allows ground-and-pound if an opponent is knocked down.<\/p>\n Rozenstruik made the most of the latter rule on Friday, as he tore through Cleveland in devastating fashion to have Dirty Boxing\u2019s unique title design<\/a> wrapped around his waist.<\/p>\n The finish came just under two minutes into the very first round and was set up by a left hand that appeared to see \u2018Bigi Boy\u2019 connect solely with his forearm to Cleveland\u2019s neck area.<\/p>\n The American was immediately on wobbly legs and collapsed to the canvas. While traditional boxing would have seen him given time to recover, there was no such escape at DBX 3.<\/p>\n Rozenstruik pounced on his stricken foe and put him to sleep with one vicious ground strike, sending the crowd into a frenzy.<\/p>\n Fans call for UFC to bring Jairzinho Rozenstruik back after latest KO away from the Octagon<\/p>\n![\"Jairzinho](\"https:\/\/www.newsbeep.com\/uk\/wp-content\/uploads\/2025\/08\/default2017-min-scaled-e1749963292616-1024x747.jpg\")
