Led with a shoulder doesn't mean automatic Red. If there are mitigating circumstances that meant onfield should have been yellow, then he will have been deemed to have been punished already and no further sanction would be applied.
It's somewhat unlikely he will play Saturday but not automatic. The judiciary has reserved it's judgement which is somewhat a good thing in my opinion. If it was clear cut, he would already know how long he was out for.
I believe it somewhat likely he will be suspended for 2 games or so.
The only mitigating factor that I can see (no i'm not the judiciary) that can possibly be applied is ball carrier suddenly dropping in height. The entire thing was so quick I don't see how he can suddenly drop in height ... but hey you could be right, though technically possible, I've never seen a Red card that did not get a suspension for as long as I've watched rugby, though that doesn't mean it has never happened!
