You learn something new every day. Can't believe they were introduced that late!red and yellow cards not used in English football until 1976 the season after this game, even though used in world cup from 1970.
That is earlier on in the clip, looked exactly like we see nowadays, huge exaggerated fall, legs flailing...This punch up was a result of Francis Lee diving to win a penalty, when Norman Hunter had not touched him. Diving was far rarer back then but Francis Lee was known for it and if memory serves me right I think he scored a record 13 penalties in one season.
At local level, they didn't come in until late 1980's.....You learn something new every day. Can't believe they were introduced that late!
