If there was any concern that Conor McGregor wanted to stay "retired," we can put that to rest.
Despite the UFC's official stance that McGregor will no longer participate in UFC 200, it doesn't sound like the two parties are done with each other just yet. McGregor has followed up on that infamous tweet that started all of this with another. In it, he seems to issue an open challenge to the UFC brass.
As of now, Conor McGregor is not officially set to face Nate Diaz at UFC 200. From the sound of it though, both the UFC and McGregor are just waiting to see which one of them blinks first.
