Okay, I'm fairly new to the world of football manager so bear with me please.
Basically the last match I was playing my GK got a red card and was therefore sent off. The game wouldn't let me continue without another goal keeper but because he was red carded it wouldn't let me substitute him. Is there a way around this? I had to forfit a game I was winning 4-0. I'm really not impressed!

couldnt you drag another player from another position on the pitch into GK and then substitute them for your backup GK?
