Floyd Mayweather Jr. may have more invested in Monday night’s Heat-Pacers game than any of the players who will actually be on the court playing.

That’s because Mayweather bet $5.9 million on the Heat to cover, according to Vegas Gambling Steam. The line was at -7 when Mayweather laid down the bet. So not only is the undefeated boxer looking for Miami to win, but he’s looking for them to win big.

The Heat are returning home after dropping Game 6 in Indiana. Miami has lost two home games during the 2013 postseason.

Of course, what’s $5.9 million to a boxer projected to earn $90 million in 2013? Well, still a ton of money.
