Floyd Mayweather, Jr. vs. Manny Pacquiao, billed as Battle for Greatness or The Fight of the Century, was a professional boxing match between the eight-division world champion Manny Pacquiao and undefeated, five-division world champion Floyd Mayweather, Jr. The fight took place on May 2, 2015 at the MGM Grand Garden Arena in Las Vegas, Nevada. Despite predictions that Mayweather–Pacquiao would be the highest grossing fight in history as early as 2009, disagreements between the two boxers' camps on terms for the fight prevented the bout from coming to fruition until 2015. The failure to make the Mayweather–Pacquiao fight was named The Ring magazine Event of the Year for 2010. By 2015 negotiations for fight had been finalized, with all of the major issues that have prevented the fight from happening in the past resolved, including purse split, drug testing, and location. On February 20, 2015, Mayweather confirmed on social media that the fight had indeed been signed by him as Pacquiao already had signed the contract of the fight previously and the contract itself was with Mayweather on that day. The contest was agreed to be held on May 2, 2015.

Tyson Fury insisted confidently beforehand that he would take the heavyweight championship of the world from Wladimir Klitschko, and few outside of the United Kingdom (and not too many there, either) believed him. He promised that when he won, he would sing a song in the ring, and it's doubtful many paid attention to him when he said that because, well, Fury said and did a lot of things-including, but not limited to, showing up to a press conference dressed as Batman-and why would anyone focus on what he said he would do after something no one thought he could achieve?
