Watch Mayweather vs Canelo full fight video preview online for 'The One' Showtime boxing PPV in Las Vegas

In the absence of Manny Pacquiao, Saul "Canelo" Alvarez is perhaps the best possible fight fans could ask for when choosing who would challenge Floyd Mayweather Jr. for his distinction as the top pound-for-pound boxer in the sport today.

And so that's what we'll get, as the two are all set to hook 'em up later on this evening (Sat., Sept. 14, 2013) at MGM Grand Garden Arena in Las Vegas, Nevada.

There's reason to believe Mayweather vs. Canelo be a competitive fight. Sure, you likely heard something similar in the early stages of promotion for Mayweather vs. Miguel Cotto or Mayweather vs. Robert Guerrero, but consider this: "Money" was favored -650 against the latter and -800 against the former.

Against Canelo? He's just a -280 favorite.

Still, the general consensus seems to be that the fight is Mayweather's to lose. Even Andre Ward, one of the best boxers in the world, hypothesized that Alvarez will have to land a lucky punch to win.

Perhaps he's right. Or maybe he's wrong and "Canelo" will shock the world and take his place at the throne as the greatest boxer in the world today.

Stay tuned.
