Conor McGregor and Michael Chandler seemingly had a run-in whilst coaching against each other on the UFC's reality TV show ahead of their fight.
The rivals are currently filming season 31 of The Ultimate Fighter together in Las Vegas before they meet in the octagon later this year. McGregor will look to pick up his first UFC win in over three years when he faces Chandler, who has a UFC record of two wins and three losses.
McGregor and Chandler seemed to be on good terms but things changed as they recently had a fall-out, according to UFC boss Dana White. Whilst speaking to reporters including Mirror Fighting following the conclusion of UFC 285 on Saturday night, White revealed that "s** went down" between McGregor and Chandler whilst they filmed an episode of The Ultimate Fighter together.
