Floyd Mayweather and Conor McGregor will battle Saturday in Vegas
Floyd Mayweather Jr. and Conor McGregor got together for their final pre-fight news conference to further hype a fight built on hype.
In contrast to the bombastic tone of earlier appearances, it was a relatively subdued affair at the M-G-M Grand in Las Vegas.
McGregor says Mayweather will regret agreeing to this fight once it starts.
McGregor says he is ready to go all 12 rounds but doesn't expect the bout to last that long. The welterweight boxing match is set for Saturday at T-Mobile Arena in Las Vegas. Mayweather went 49-and-0 including 26 knockouts before retiring from boxing in 2015.
McGregor is 21-and-3 in the UFC and a two-weight champion but has never boxed professionally.
Online betting sites view Conor McGregor as the clear underdog in Saturday's fight in Las Vegas.
The event is expected to bring in more than 600-million dollars and fans are betting on every aspect of the fight.
