O'Malley will be upset if McGregor doesn't fight in UFC 300 main event

“If Conor isn’t at UFC 300, it will be such a disappointment... It doesn’t matter if it’s Conor vs. Chandler or Conor vs. Gaethje, but Conor’s fight has to be the main event of UFC 300, otherwise I’m not watching. Just kidding, of course, I’ll watch, but I’ll be sad,” Sean said.

Let us remind you that it was previously reported that UFC 300 will take place in April next year.
