Youtube star Jake Paul has now taken aim at cruiserweight prospect Tommy Fury, who is the younger brother of WBC heavyweight champion Tyson Fury.

Paul and Fury have been trading worlds on social media in the last few weeks.

The feud first began when Tyson Fury called for a fight between his younger brother and Paul.

Tommy Fury recently raised his record to 5-0 with four wins by knockout. Father/head trainer John Fury and promoter Frank Warren are both on board with making the Paul fight happen.

Paul is 2-0 as a pro and returns for his third fight on April 17th against MMA veteran Ben Askren.

As far as the future goes, Paul is not ruling out the possibility of facing Tommy Fury. 

"It's not very serious, he's a little brother living in his big brother's shadow, literally and figuratively," Paul told IFL TV. 

"He's smaller in every single way, and the kid wasn't even man enough to call me out himself, he had to have his big brother do it.  Pretty embarrassing. But hey, who knows? Maybe the fight happens one day. It could be interesting." 

Tyson Fury believes the contest between his younger sibling and Paul is pretty even.

“Jake Paul can fight I'll have you know. I think they have about the same level of experience. They have both had a few pro fights, Tommy had a limited amateur background, ten fights or something. I think it would be an even fight to be fair," Tyson Fury said.
