Within minutes of McGregor's comments, Paul responded by calling out the former UFC champion.
"Buddy you need to get into rehab and then USADA," he tweeted. "Until then shut the f**k up. Floyd toyed with you. Dustin chinned you up. Khabib and Nate choked you out. And I would put you in the coffin for good even as juiced up as you are."
Jake Paul told Conor McGregor to 'get into rehab' after boxing comments
Paul was responding to McGregor's many tweets, including one where McGregor said the fight was "absolute garbage."
Paul also shared a photo of McGregor getting rear-naked choked by Diaz next to a photo of himself knocking Diaz down.
We're not sure who we want to see more ... a rematch between Diaz and McGregor or McGregor back in the ring, this time with Paul.
It's unclear what's next for Diaz, but a second fight with Paul, this time in MMA is what the fans and Paul wants (he's even put a $10 million offer on the table for it).
