Just to give an example. Once playing a Yorkshire League game, centre-forward. Defender came in, sliding tackle, right foot knee high. Managed to avoid his studs and as my right foot returned to earth, I stamped heavily on his left ankle. I heard him whinging to the referee and the referee saying 'what do you expect when you tried to break his leg'. Those were the days.1950's/60's. When someone clogged you, you could clog them back and not get sent off.
