As noted, UFC Interim light heavyweight champion Jon Jones has been pulled from his fight against UFC light heavyweight champion Daniel Cormier at UFC 200 this Saturday due to a potential doping violation. USADA, the U.S. Anti-Doping Agency, informed Jones of the potential violation today which stemmed from an out-of-competition sample collection on June 16, 2016. UFC President Dana White announced that Brock Lesnar vs. Mark Hunt is now the main event for Saturday's show, and it will remain a three-round fight.
