Conor McGregor took to twitter today to blast Chatri Sityodtong. The Irishman is upset about the UFC dissolving its flyweight division and feels the ONE Championship CEO is directly to blame,

ONE Championship recently signed former UFC flyweight champion Demetrious Johnson. ‘Mighty Mouse’ is widely regarded as the best fighter in divisional history but his former employers decided to trade him for undefeated welterweight Ben Askren.

McGregor appears to feel that this makes ONE Championship responsible for the widely reported demise of the UFC flyweight division. Reigning champion Henry Cejudo is expected to move up to bantamweight while the remainder of the roster might well be released.

Johnson is set to participate in an eight man flyweight Grand Prix organized by ONE Championship. It means he is likely to fight three times in 2019, assuming that the former UFC flyweight champion wins all his tournament matches.

His former colleagues face a much more uncertain future. Jose Torres and Jarred Brooks are both reported to have been released and any UFC flyweights that aren’t willing or able to move up a division will probably face a similar fate.
