This could very well be the biggest sparring match in the history of boxing.

Just 24 hours ahead of the three round exhibition bout in Japan Mayweather and his kickboxing world champion opponent have now faced off:

There was thought to be thousands a short time ago in attendance in Japan just to see the two square off.

Mayweather seems to have cut America out of the equation completely however with the fight seemingly not able for legal viewing tomorrow for those in the US.

Unless he pulls a last minute bag out of the hat he’s wearing above of course.

Don’t rule that out either.

You just never know with Floyd Mayweather.

Who knows what’s really going to happen in this spectacle tomorrow in Tokyo.
