Continuing to rumble on in their newfound rivalry, former undisputed duel-weight UFC champion, Conor McGregor has labelled veteran welterweight contender, Matt Brown a “heroin addict” – in a jab aimed at the Ohio native’s prior substance abuse issues. 

McGregor, a former undisputed lightweight and featherweight champion under the UFC banner, has been sidelined from the Octagon since fracturing his left tibia and fibula against Dustin Poirier at UFC 264 back in July 2021.

Expected to make his Octagon comeback before the close of this year in a welterweight fight against former lightweight title challenger, Michael Chandler, McGregor appeared to take notice of the above-mentioned, Brown’s recent record-setting KO win over Court McGee at UFC Fight Night Charlotte earlier this month.
