Training could be a problem, who knows?
Remember though, game conditioning and practice/training is a HUGE difference. Once you get use to \"game conditions\", play faster, much bigger effort, hit harder, adrenilin way up, mental strain etc, then you won't see fatique from the players. Huge difference. Game conditions create short term fatique from the adrenilin rush and excitement. They will be fine on that front.
