The Welsh Rugby Union have issued a lifetime ban to the supporter who invaded the pitch during Saturday's defeat to South Africa at the Principality Stadium.
The man was tackled to the ground by stewards in the 63rd minute of the game, having climbed over the advertising boards and running onto the pitch, reportedly for a £20 bet.
His presence on the pitch interfered with a potential tryscoring opportunity for Wales. The scores had been 15-15 at the time of the incident, with Wales going on to lose 23-18.
The incident drew anger from the supporters in attendance, with many throwing objects at him as he was dragged from the field.
This evening, a statement from the Principality Stadium manager Mark Williams said the man in question has been banned for life from attending Wales matches at the ground.
"The WRU, Principality Stadium and South Wales Police condemns any behaviour of this kind, and the individual will be issued with a lifetime ban from buying any tickets from the WRU for rugby events held at Principality Stadium in future.
"We were deeply disappointed to discover the individual is a registered player and member of a rugby club; and the WRU are currently investigating this as a Code of Conduct breach.
"I'd like to thank the pitch side stewards and on pitch security team who acted swiftly stopping the individual and escorting them from the field of play.
"For more than 20 years this stadium has been revered across the world for its unique atmosphere and game day experience. It's extremely disappointing to think that by recent events the traditional game day experience is under threat and that we might be forced to look at additional measures that will impact on the fan experience in future," his statement reads.
It was the second time in a week that pitchside security had been breached in Cardiff, after a Youtube prankster invaded the pitch prior to their meeting with the All Blacks on 30 October. The same person also lined up alongside Japan's players last Saturday, prior to their meeting with Ireland at the Aviva Stadium.
