A couple of things...
1. Mortimer was never going to come back this weekend, he is stilll recovering despite having a training run. All the youngsters need to play well enough to keep their spots (Elgey and Moseley). A Moseley/Mortimer rotation might be fun.
2. Perhaps the hooker rotation aint such a bad thing. I always admired Socceroos coach Guus Hiddink because of his ability to inject energy at crucial times during a game. Moseley coming off the bench when the big forwards are tiring may work ok.
