Yeah but Gardner initially did not call it a penalty as that was a normal tackle hes seen many times before down here. He was tipped by someone to review it. I think it was a sideline official.
I found it annoying because it was a beautiful tackle and that killed it a little. Farrell should of been celebrating the win after that hit.
I think it was either Ben Whitehouse (Welsh) who is not the best ref if said politely or the TMO who was Irish. IMO I felt it needed looking at for where the contact was made, not for the tackle itself. If he had made contact with the head then it would have been a red regardless of trying of trying to wrap the arms by the letter of the law.
