In an update on WWE superstar and former UFC Heavyweight Champion Brock Lesnar facing off against Mark Hunt at this Saturday’s UFC 200 mega event, the fight has now been pushed to the main event after UFC Interim Light Heavyweight Champion Jon Jones was notified by the USADA (United States Anti-Doping Agency) that he has potentially failed a pre-fight drug test and therefore has been pulled from the event this weekend.

UFC President Dana White noted that the UFC are looking for someone to step up and take the fight on short notice against Daniel Cormier, Jones’ original opponent, with UFC Light Heavyweight star Alexander Gustafsson and current UFC Middleweight Champion Michael Bisping amongst those campaigning on Twitter for the fight against Cormier.

If Jones has indeed proven to have failed, then he will be suspended for a mandatory two years, meaning that he would not be permitted to fight for any mixed martial arts organization until July 2018.
