For almost his entire career spent in the UFC, Anderson Silva often talked about his dream to crossover to boxing and potentially pursue a fight against multi-weight class champion Roy Jones Jr.
At the time, Silva was on top of the world as the best middleweight in the UFC and arguably the top pound-for-pound fighter in all of mixed martial arts, which meant there was little chance the promotion was going to allow him to take a risky boxing match while he was still serving as their champion.
Years later, the UFC allowed Conor McGregor to engage in a boxing match with Floyd Mayweather but Silva never got the chance until he left the organization and received an interesting call while he was on vacation with his family.
