I have never seen a GK get injured in a game or get a card,that includes for a back pass....
Don't even know why I bother bringing a substitute goalie to games..
Yeh I've just had my keeper grab the ball and slide out of the box, got yellow carded for hand ball. First time i'd seen it, havent seen a backpass yet, but im not very observant.
I saw it happen when I used Barca against some rubbish team. Put pressure on him and he picked it outside the box. I got a free kick and the GK got a yellow card!
