One of the best parts about paying to see a fight is that the violence will stay far, far away from you. Those two insane people can beat each other to a pulp, but you're not going to have to test your own loyalty to your friend when someone puts them in a choke-hold.
But that was not the case in Manchester on Saturday at a fight between Tyson Fury and Sefer Seferi. A rumble broke out in the crowd, and it grew and grew into a battle royal. It was so huge that the boxers were distracted from literally beating each other into submission with their fists and watched for a bit.
