Following Islam Makhachev's emphatic victory over Alexander Volkanovski at UFC 284, the Dagestani has been leveled with serious allegations by Dan Hooker. The Aucklander claims that he has substantial evidence that Makhachev used intravenous (IV) therapy to replenish himself after the weigh-ins, which has been an illegal practice since USADA was introduced as the UFC’s anti-doping partner in late 2015.This past weekend, Makhachev defeated Alexander Volkanovski, the reigning featherweight champion, and scored a hard-fought unanimous decision victory to defend his lightweight title. Hooker, who traveled to Perth to root for City Kickboxing teammate Volkanovski, is convinced that Makhachev cheated to gain an unfair advantage in their upcoming bout. The allegations emerge at a time when narratives are ripe that Volkanvski was perhaps "robbed" by the unanimous decision.Dan Hangman Hooker@danthehangmanDumb cunt thinks he can fly to Australia hire a nurse to give him an I.V and we won’t find out.
