Mayweather vs Canelo results: Full fight coverage stream LIVE online for Showtime PPV main event TONIGHT!

It's finally here!

All the media coverage, press conferences and snappy one-liners are over ... it's now time for the most anticipated boxing event of 2013.

THE ONE!

Top pound-for-pound fighter in the world, Floyd Mayweather Jr., will take on unbeaten Mexican sensation Saul "Canelo" Alvarez in a 152-pound catchweight championship clash for the ages TONIGHT (Sept. 14, 2013) from MGM Grand Garden Arena in Las Vegas, Nevada.

MMAmania will deliver LIVE coverage of "Mayweather vs. Canelo" main event below!

In addition to the bragging rights, sponsorships and places in history undoubtedly at stake, the winner of Mayweather vs. Canelo will receive -- no joke -- a solid gold belt from the WBC, whose Junior Middleweight title Alvarez picked up off of Matthew Hatton in 2011, which will be on the line.

On the more mundane side, the winner will also get Alvarez's WBA "Super World" title, briefly held by Mayweather after defeating Miguel Cotto. It's best not to puzzle out exactly what "Super World" means. Interestingly, Alvarez is just two years older than Mayweather was when Floyd picked up his first title, defeating Genaro Hernandez in 1998.

Enough talk ... Let's get it on!
