The MGM Grand Garden Arena in Las Vegas will be packed to the rafters on Saturday night as Floyd Mayweather and Manny Pacquiao meet for the most anticipated fight in boxing history. The final press conference is scheduled for Wednesday afternoon, marking the second time the fighters will meet face to face since announcing the fight. The fighters, their promoters, and their trainers are all expected to be on stage for the press conference.

Mayweather is currently boxing’s top box-office draw. He’s undefeated and has remained virtually unchallenged for quite some time, being well known for his technical style built on defensive counterpunching. Pacquiao has long been viewed as the primary threat to Mayweather’s dominance of the boxing world due to his speed, power and swarming style.

Both men will be looking for a decisive result to finally put a stamp on their epic rivalry. Mayweather will put his WBC and WBA welterweight championships on the line against Pacquiao’s WBO version of the 147-pound title. In comments to Showtime made in December, Mayweather made it clear that he wanted the fight with Pacquiao for both legacy and financial reasons.

The anticipation for the “Fight of the Century” has resulted in related events also seeing high demand for attendance. Viewing parties have been planned all over the country, with some charging ticket prices more expensive than those for the fight itself.

The pre-fight weigh-in will take place at the MGM Grand Garden Arena on Friday, May 1, the day before the fight. While weigh-ins for boxing matches in Las Vegas are typically free to the public and assigned on a first come, first serve basis, the popularity of this fight resulted in an exception being made to prevent a mass amount of people camping out for the free tickets.

The weigh-in tickets were priced at $10 with all proceeds going to a charity of each boxer’s choice – the Cleveland Clinic Lou Ruvo Center for Brain Health for Pacquiao and the Susan B. Komen for the Cure foundation for Mayweather. More than 10,000 tickets were sold for the weigh-in.
