How Australia approaches Reece Hodge's citing will be interesting.
Seemingly they will have to plead it was a yellow card only offence for him to get away with no suspension. This will be difficult as they initially need to show that it wasn't a shoulder charge because his arms were wrapping sufficiently. They then need to convince the commissioners that it wasn't a high degree of danger.
This gets into the more subjective elements of what was involved in Hodge's tackle.
Personally I think the Wallabies will need to consider what the likely outcome is for pleading guilty. It would certainly be to miss the Wales game but that could be it. Certainly he'd be back before the quarter finals. I tend to think this is the sort of outcome they need to go for and then just move on. There's also the issue that if you fight to get Hodge off his charge and play him, you've had enough uncertainty for enough of the week that it proves disruptive anyway.
