Boxer Floyd Mayweather Wheels Massive Tray of Cash to Car in Las Vegas

Floyd Mayweather Jr. remains the world’s richest athlete now that he’s out of retirement, he says, to box MMA superstar Conor McGregor.

On Thursday, the 40-year-old, known as Money, was seen wheeling a tray of cash into his car in Las Vegas as "he gets everything lined up for the opening of his new gentleman's club, ‘Girl Collection.'"

Mayweather told TMZ earlier this week that the Irish lightweight titleholder would have a chance in the boxing ring.

It seems the boxer will keep himself plenty busy as negotiations with McGregor continue.
