Rampage Jackson, UFC legend, said that Jake and Logan Paul "resuscitated boxing" because it was "not exciting anymore" following Mike Tyson's retirement.
The American brothers have turned their social media success into prizefighting.
It has been praised by Jackson, a former UFC champion, who said boxing was behind its competitors after Tyson, now 55 years old, quit the sport.
South China Morning Post was told by he: "I think they are very entertaining. They seem to have revived boxing.
"I have all due respect for all boxers, even though I'm MMA every day, I represent MMA, and we got a battle against boxers right now. I don't hate boxers, or the sport of Boxing.
"Boxing is a great craft. I have been trading it for at least 15 years. It wasn't as exciting after Mike Tyson quit boxing."

The draw was their first since the American lost the rematch in scrappy split-decision a year later after becoming professional.
He returned to boxing in June last year for an exceptional exhibition against Floyd Mayweather, 45.
Surprisingly, even more, defeat can be technically avoided.
