Infamous YouTuber Jake Paul is feeling pretty good about himself after executing a highlight reel-worthy knockout against former NBA player Nate Robison in their exhibition match last Saturday. However, he might be biting off more than he can chew after issuing a challenge to two professional mixed martial artists.

Shortly after his second-round KO win in the Mike Tyson-Roy Jones Jr. undercard, Paul called out former UFC Lightweight and Featherweight champion Conor McGregor and his teammate Dillon Danis to step into the ring with him next. Per a report from Triller, via George Flood of Yahoo News:

“I’ve been training my ass off, for the past year. I’m taking this seriously,” the 23-year-old internet celebrity said. “There’s a long list of opponents that I want – Conor McGregor, Dillon Danis, I’m going to knock them both out.”

In the event that he doesn’t get the blockbuster fights, Paul said he also wants to avenge the defeat of his older brother Logan Paul to rapper KSI or take on social media influencer Austin McBroom. Furthermore, Paul revealed that he broke his nose meditating heading into the bout and could only spar three days before facing Robinson.

Sure, sending an elite athlete like Nate Robinson face-planting to the canvass is one impressive feat. Still, it is worth noting that Robinson has never participated in a combat sport ever in his life. Legitimate fighters like McGregor and Danis have pretty much been fighting for the majority of their existence. There are certainly levels to this game, and Jake Paul might learn that the hard way if he faces these two fighters in the ring.
