It won't be much good to Wales now but World Rugby have admitted that an error was made by the Television Match Official in chalking out a Welsh try in the tight 12-6 loss to England in last weekend's Six Nations match.
And it raises the spectre of controversial refereeing calls in rugby and it's something both former Ireland captain Keith Wood and ex-Ulster and Ireland flanker Stephen Ferris felt very strongly about as they discussed the issue on Wednesday Night Rugby with Joe.
On the wider point around TMOs and refereeing decisions, Keith said, "When it comes to a discussion point with the TMO, how good is that guy? Is he an international referee to be making that call or that adjudication on that incidence. It still needs to go back. It should be down to the ref's call so Garces should have made that call himself: 'Well, I actually think it is a try".
Ferris also discussed his own personal experience from his Ireland days.
"Wales are coming to the Aviva Stadium in a week and a half. You know, it wasn't that long ago where Wayne Barnes penalised me for a tip tackle at the end of the game and a letter came back a week later after Leigh Halfpenny slotted three points for them to win and that was the opening game and they went on to win the Grand Slam and the letter came apologising that more or less a refereeing decision had cost us the game because I'd been proven innocent that it wasn't a tip tackle," said Ferris.
"So refereeing decisions, it cannot get to the stage where they're deciding a Championship so I totally agree with Keith. That was a try. Would Wales have gone on to win that match? I probably don't think they would have. However, at that time they could have got a little bit of momentum and hindsight's a wonderful thing. But referee decisions, it needs to be looked at. We keep talking about it. It keeps coming up on everything to do with rugby and I just think it needs to be addressed and for it to be nailed down because it's just not good enough."
