Wales were left bemused by a critical decision in their dramatic 32-29 defeat to South Africa last weekend and have sought answers from World Rugby on the matter.
Louis Rees-Zammit was one of four Welsh players shown a yellow card by inexperienced referee Nika Amashukeli after he made a try-saving tackle on Willie Le Roux and appeared to make a textbook jackal over the ball deep in his own 22. But the Georgian official felt the speedster did not release the tackled player before going in on the ball and sent him to the naughty step.
Wales were leading by two points with eight minutes remaining at the time of the decision and a penalty try for the hosts came two minutes later, giving them the lead for the first time in the match.
