Ryan Kavanaugh, co-founder of the Triller app, has been advised by several sources that Mike Tyson "fears" the scenario of having a trilogy fight with Evander Holyfield.

Triller is staging another pay-per-view event this coming Saturday night, when Holyfield steps in on late notice to face former UFC champion Vitor Belfort in a boxing match.

Holyfield, 58, tried to secure a trilogy fight with Tyson - but their respective teams were never able to reach an agreement on the monetary terms.

In 1996, Holyfield stopped Tyson in eleven round to capture the heavyweight title in a major upset.

A year later, their famous rematch took place, with Tyson being disqualified in the third round for biting off a piece of Holyfield's ear. 

Tyson headlined a Triller PPV last year, when at age 54 he returned to the ring to fight to an eight round draw with Roy Jones Jr. in an exhibition clash.

In the aftermath, Tyson had a falling out with Triller and took shots at their company in an interview.

According to Kavanaugh, Tyson is trying to stage a fight with Lennox Lewis, who stopped Tyson in 2002.

"We know he is trying to stage a fight with Lennox Lewis," Kavanaugh told Sky Sports.

"We have been told that he is scared to fight Evander. There has been back and forth hoopla, there is a massive payday ready for Mike to fight on Thanksgiving. A massive payday, one of his biggest! But we can't seem to push it along. Now I have heard, from a number of reliable sources, that Mike is too scared. He thinks Evander would knock him out. We have an offer out to Mike [to fight Holyfield].

"I wouldn't ask nobody to do anything they don't want to do. But it's for charity. If we can work something out that works for everybody then it's a win-win-win."
