One of the biggest boxing fights is going down Saturday and fans will be able to watch events leading up to "The One: Mayweather vs. Canelo" mega event.

Fans can watch the weigh-in Friday at 5PM/ 2PM ET on Showtime Sports.

Eight-time, five-division World Champion Floyd "Money" Mayweather will go face-to-face with Super Welterweight World Champion Canelo Alvarez in one of the biggest sporting events of the year.

What's at stake Saturday are Canelo's WBC, WBA and Ring Magazine Super Welterweight World Championships and Mayweather's WBA Super Welterweight Super World Championship.

Mayweather will have a good luck charm by his side, as TMZ reported that singer Justin Bieber will walk the boxer to the ring before his championship match at the MGM Grand Garden in Las Vegas, Nev.

Last year, Bieber attended Mayweather's fight againt Miguel Cotto, walking the fighter to the ring and also hanging out with him and Lil Wayne after his victory win.

The celebrity site also reported that tickets to the fight are going as high as $100,000 per seat.

Luckily for fans around the country, they will be able to pay a much smaller fee of about $70 if they subscribe to the fight via their cable provider.

Mike Tyson, former heavy weight champion said he is predicting that Mayweather will come out with the win.

"I've only seen Canelo fight twice -- against [Joselito] Lopez and [Austin] Trout. Trout gave him some trouble and he isn't as experienced and as technically skilled as Floyd is. Floyd stays in tip-top shape and is a very relaxed fighter. He is at his peak. It's going to be hard for anybody to beat Floyd now unless he doesn't train. Floyd has transcended the game so much that the best fighters out there now try to emulate his style. Floyd wins by a decision."
