It’s happened twice. First time around 25 years ago. Mass confrontation which ended up with 9 red cards.Be interested to hear about the game(s) you had to abandon due to less than 7 players for a team. The closest I've come to was a team starting with eight and I had to reluctantly send one of them off for DOG handball.
Second time was last season.
Player sent off in the first half, used all 3 named subs at half time, then 4 players got injured leaving them with 6
