Takes 8min game time for the engine to react to a sub, waste of time, I had to replace a palyer last night 20min to go cartilage damage, the sub never got a kick he was injured after 5min twisted anckle, waste of time fighting the game engine with injuries, next time I'm playing with 10, I was leading in any case and still won 3-0 so I doubt much would have changed even without the sub, stuff the rest pack.
