> The Football Association was established at a fiery meeting in which the rules of football were laid down. Blackheath FC were overruled in their wish to allow "hacking" (kicking an opponent in the leg)

That developed into its own, less popular, sport.

> Shin-kicking, also known as hacking[1] or purring, is a combat sport that involves two contestants attempting to kick each other on the shin in order to force their opponent to the ground. It has been described as an English martial art.[1] It originated in England in the early 17th century, and was one of the most popular events at the Cotswold Olympic Games until the Games ended in the 1850s.[2]
