Floyd Mayweather versus Zab Judah in 2006 was a fight that nearly ended in a riot.
The IBF welterweight championship bout took place at the Thomas and Mack Center in Paradise, Nevada and it will also be remembered as one of Mayweather's toughest.
The Money Man eventually prevailed courtesy of a unanimous decision, but Judah proved to be a stern test for the the legendary fighter.
However, the meeting between the two enemies will always be associated with the scenes that erupted during the 10th round.
Mayweather was comfortably ahead on the judges scorecards and it was clear that Judah was getting frustrated with his adversary's slick movement and cunning tactics.
So in response, Judah delivered a powerful low blow, before aiming a right-hand to the back of Mayweather's head straight after.
The referee immediately called timeout, with Mayweather visibly in agony and hopping around the ring. What followed was absolute chaos.
Floyd's uncle, Roger Mayweather, vaulted the ropes to square up to Judah and a full-scale riot almost broke out.

Madness! Yoel Judah's entry into the ring is where things really kick off. Zab's father aims a punch at Mayweather's uncle, prompting all parties from each team to enter the ring to join the melee.
Roger was eventually ejected from ringside and Judah's promoter, Don King, believed that the fact Mayweather's uncle was the first person to enter the ring should have seen Floyd disqualified from the fight.
The iconic 50-0-0 fighter actually escaped without punishment, but his uncle Roger received a $200,000 fine and saw his boxing licence revoked for one-year.
Judah also saw his licence revoked for 12 months by the Nevada State Athletic Commission and he also received a $35,000 fine for his part in the melee.
Mayweather really knew how to get under his opponent's skin, didn't he?
