The Mayweather-McGregor fight ended in 10th round in which Mayweather won on technical knock-out.

Mayweather's prediction was spot on. Imagine if he somehow had agreed to fight middleweight monster Gennady Golovkin. Reports indicated he would earn a minimum of £78million from the McGregor fight, to add to his estimated pre-fight net worth of £263million. But not all viewing went smoothly.
