One of the first angles shown it looked like the initial contact was shoulder to shoulder which rode up to shoulder-head, and given the impact wasn’t strong he had gone down just could have gone down more, plus the Irish player dipped a little I’m hopeful that commonsense will prevail and it will remain yellow. After all previous Ireland-New Zealand test matches have shown you can make a completely upright tackle, concuss & break the check of the opposition player and it is a confirmed yellow only.
