In 2009, former UFC Heavyweight Champion Tim Sylvia fought former heavyweight boxing champion Ray Mercer.
Mercer took less than 10 seconds to knockout the former UFC champion in an MMA fight.
In the video below, you can watch Mercer shock the world when he took his knockout power and transferred it into the world of MMA.
Later this month, UFC Lightweight Champion Conor McGregor will be taking his knockout power and will be seeing if he can transfer it into the world of boxing.
McGregor lethal striking abilities have led to him knocking out two UFC champions. McGregor’s knockout wins over Jose Aldo and Eddie Alvarez led to McGregor being the only fighter in UFC history to hold two different UFC titles at the same time.
Mercer’s fight with Sylvia proves that fighters from one sport can knockout fighters from another. However, it also shows that boxers may be the superior strikers.
Mayweather vs. McGregor will take place Aug. 26 at the T-Mobile Arena in Las Vegas.
