Former two-weight UFC champion, Conor McGregor has hit out at promotional color-commentator, Joe Rogan, after the latter questioned if the Dubliner was utilizing PEDs (performance-enhancing drugs) to aid his recovery from a fractured tibia and fibula suffered in July of last year.

McGregor, 34, has been sidelined since UFC 264 last year, headlining against former interim lightweight champion, Dustin Poirier.

Suffering a first round doctor’s stoppage TKO loss in the pair’s rubber match trilogy bout, McGregor suffered a fracture of his left tibia and fibula in the opening frame.

In the time since, McGregor, who has yet to be subject to anti-doping testing by anti-doping agency, USADA (United States Anti-Doping Agency) since the third quarter of last year, has experienced a significant mass and size increase, leading many in the community to speculate that the Crumlin native is utilizing PEDs to help recover from his injury. 

Rogan, a staple in the promotion’s commentary booth recently addressed the former undisputed lightweight and featherweight champion’s drastic weight increase, joking how a urine sample provided by McGregor would likely melt through a USADA testing apparatus.
