Spectacle, freak show, money grab, call it what you want, but UFC two-division champion and undefeated legend Floyd Mayweather are fighting on August 26, and there's nothing anyone can do about it.

Already on pace to become the highest-selling pay-per-view fight of all time, the historic Mayweather vs. McGregor bout, which will be conducted under boxing rules and in a boxing ring, sees "The Notorious," a mixed martial arts supernova, ascend to the greatest heights in combat sports to take on "Money," a master of the sweet science, who has gone 49-0 during his illustrious career.

With less than two months until the biggest crossover fight since Muhammad Ali fought Antonio Inoki in the wrestling ring in 1976, both McGregor and Mayweather are honing their skills. For McGregor, this will be his first professional outing inside the boxing ring, while Mayweather returns to action after two years on the sidelines, following a brief retirement.
