Savage ! Conor McGregor trolls Floyd Mayweather by hitting him where it hurts

 The pre-fight battle between Conor McGregor Floyd Mayweather is heating up as McGregor has taken a swipe at Floyd by reminding the world of the latter's domestic abuse conviction.

Ahead of the pair's £500million mega-fight, the UFC champion rocked a Golden State Warriors basketball shirt with C.J. Watson's No.23 number.

Here is where it gets interesting,!
Watson was alleged to have been sleeping with Mayweather's girlfriend in 2010, which  resulted in the the boxer assaulting the mother of his three children, Josie Harris.

Mayweather plead guilty to domestic assault charges and was sentenced to 90 days in prison, serving half.

The Warriors' current No.23, Draymond Green saw the post and commented: "We rocking with Floyd bro not you... that off bruh."

But McGregor responded: "That's C.J. Watson mate. I don't know who the f*** you are. No disrespect tho kid, keep hustling and stay in school.

Ouch!
