Logan Paul has cooled on the idea of fighting controversial NFL free agent Antonio Brown and is unsure whether his brother Jake wants to follow in his footsteps and face KSI in the boxing ring.

Earlier this year, former New England Patriots and Pittsburgh Steelers running back Brown and YouTube sensation Paul teased the prospect of going head to head.

"Should I fight @LoganPaul for 4.1m with possibly 8.2m raise?! I'll donate proceeds to charity...he keep coming at me about this non-stop," Brown posted on Twitter in February.

Paul responded: "If you do, I'll match your donation."

However, Paul – speaking in an Instagram interview with Matchroom promoter Eddie Hearn – conceded the chances of a fight that would draw many intrigued eyes are increasingly slim.

"I realised that Antonio Brown is just clinging on to my name to get some clout for a second while he figures out his life," Paul said.

"When I figured out he doesn't actually want to fight me, because he's worried he'd lose and I'm confident I would beat the s*** out of him, I kinda backed off."

Paul was famously beaten by fellow YouTuber KSI in Los Angeles last November, with their first bout in the amateur ranks having ended in a draw, and sibling Jake Paul has since spoken of his desire to take on the Briton.

Speaking about the possibility of his young brother facing KSI, Paul replied: "It's on JJ (KSI).

"I don't know what he's planning on doing. I know he's making music right now.

"Jake wants to do it. I think it'd be a great fight. I also think Jake would take the W on that one, but it just depends on if KSI is done with boxing or not."

Paul's own combat ambitions remain and earlier this year he documented a sparring session with UFC star Paulo Costa.

It ended with Costa knocking Paul out cold, but that has not dampened his enthusiasm to enter the brutal world of MMA.

"That's my secret, bro," Paul said of his background in wrestling.

"I need to do one MMA fight before I die and I would love to do it with Matchroom Boxing or Matchroom MMA."
