Islam Makhachev retained his lightweight strap with a unanimous decision win over Alexander Volkanovski in the main-event at UFC 284 in Perth. Volkanovski's teammate from City Kickboxing, Dan Hooker, made some serious cheating allegations about Makhachev in the aftermath of the event. 'The Hangman' accused Makhachev of using an intravenous (IV) to rehydrate after he weighed in. Makhachev's co-manager, Rizvan Magomedov, has now strongly denied all allegations of cheating, labeling Hooker a 'salty' loser looking for attention. Magomedov said in a statement to MMA Junkie's Mike Bohn:“We all know this is completely BS. The guy is a loser. He’s salty and just looking for attention, and that’s it.”He also posted a tweet about 'Jealous losers', seemingly directed at 'The Hangman'.Rizvan Magomedov@Rizvan_RMJealous losers speeding lies, eventually this is all you can do542101Jealous losers speeding lies, eventually this is all you can doDan Hooker, who lost to Islam Makhachev at UFC 257 in 2021, accused the Dagestani of hiring a nurse to administer the IV injection.
