Conor McGregor has been accused of being "jealous" of the attention that Tom Brady has received after returning to American football from retirement after just a few weeks.
Brady, a legend of his sport, had confirmed he was quitting on February 1, but less than two weeks into March he had confirmed that he was back.
And UFC star Belal Muhammad joked that McGregor was going to react poorly to being pushed out of the headlines by Brady's shock u-turn, mocking the Irishman for a previous incident that happened at a Dublin pub.
