Just made the mistake of watching some of the Wales France match back.
1st France try both French chasers were off side.
The penalty against France (where the wing was yellow carded) wasn't a penalty try as there was a covering defender but George north @ 110kg and 15-20mph 5 meter vs a scrum half only has one winer.
There is footage on YouTube of a French players face against George's arm then he pulls his arm away violently. Not absolute evidence but very damning combined with the teeth bruising.
Then to the farce of the scrummaging, 1st the the replacement proper French 17 can be seen collapsing the scrum and binding on the arm which is now a professional foul, the ref was aware of this as he asked the prop if he was OK and he replied "ok but have a sore back", at the point he is clearly aware that he is collapsing the scrum and advantage should go to Wales. Then to top of a terrible match official performance by the entire team not just useless Wayne. French coach tells their best prop to warm up, then walks over to doctor which is outside the technical area (so not allowed to avoid exactly this), as soon as the coach is back in the tech area the doctor runs on to take 17 player off for his "head injury assesment" despite there being no incident of any kind which could lead to a head injury and the warmed up prop (who just happens to be one of the worlds best props) can return to the field.
All seems pretty ridiculous and several other irb referees have spoken out which I have never heard of before.
No official response from the wru or the irb but I would be amazed if we see Wayne or the doctor near an international match again.
