With the recent news of Floyd Mayweather fighting Conor McGregor in August, some fighters are trying to capitalise and get on the undercard.

One such fighter is UFC heavyweight champion Stipe Miocic who has challenged Anthony Joshua to a boxing match on Twitter.

The tweet created some talk about Joshua possibly fighting on the undercard but it seems like we can now put those rumours to bed. The heavyweight boxing champion has responded on social media.

“Who the fooook is that guy,” wrote Joshua.

His promoter Eddie Hearn has also given a somewhat of a direct and a simple answer when asked if Joshua will fight on the undercard.

One fan even wrote that Joshua and undercard don’t belong in the same sentence anymore.

So if there’s anything to decipher from all of this, it’s that Joshua’s focus is on the Klitschko rematch and challenges from MMA fighters are meaningless to him.
