Dana White

Mayweather extended his boxing record to 50-0 by beating UFC star Conor McGregor last year, and has recently teased a rematch inside the Octagon.

The stateside TV logistics would have caused a problem, according to the UFC's White, but those fears have been allayed.

"Nothing is off the table. The objective is to do events that do good business and, more importantly, provide good entertainment to the fans," Showtime president of sports and event programming

Stephen Espinoza told Sky Sports, despite incurring criticism from White last weekend.

UFC superstar McGregor will make his boxing debut in Las Vegas after luring Mayweather out of retirement for the blockbuster event.

Given Mayweather's 49-0 record the American has been installed as strong favourite for the fight, but McGregor's odds have continued to come in as the bout draws closer.

And UFC boss White believes McGregor is going to shock the world by knocking out his illustrious opponent, and in turn make him the "greatest combat sports star ever".

"To think Conor can't beat Floyd Mayweather is quite something," White told BBC Sport.
