The four Welsh regions have denied any agreement that Wales Captain Sam Warburton will be guaranteed to play regional rugby next season.
Former Wales player Rhys Williams has expressed his concern that players will be "used as pawns in tactical chess game" in on-going row.
WRU Chief Executive Roger Lewis has admitted the on-going dispute with the Welsh regions has tarnished the image of Welsh rugby.
It's great to have Alex and Scott available and they bring a lot of experience into the back line. Alex and the medical teams have worked really hard to ensure he is ready for this weekend and it's great to be able to bring him back into the side.
We though Owen (Williams) performed well in the centre against Tonga and he gets another opportunity on Saturday.
There is a lot of experience in the pack for what is going to be a very physical game.
– Warren Gatland, Wales Head Coach
We are looking to finish the series off well, the last three games against Australia have gone right down to the wire and I don't expect anything different this weekend.
Wales Head Coach Warren Gatland has announced his squad to face Australia early. Alex Cuthbert and Scott Williams have both returned from injury to join the starting line up for Saturday's final match in the autumn series. This will be Cuthbert's first appearance for Wales in the autumn series.
Leigh Halfpenny, Alex Cuthbert, Owen Williams, Scott Williams, George North, Dan Biggar, Mike Phillips, Gethin Jenkins, Richard Hibbard, Rhodri Jones, Alun Wyn Jones, Ian Evans, Dan Lydiate, Sam Warburton, Toby Faletau.
Ken Owens, Ryan Bevington, Samson Lee, Ryan Jones, Justin Tipuric, Rhodri Williams, Rhys Priestland, Liam Williams.
Wales could recall Lions winger Alex Cuthbert for the final autumn international against Australia. Cuthbert had been expected to miss the whole of the autumn series after suffering an ankle injury while playing for the Cardiff Blues.
The 23 year-old is set to be assessed by the Wales doctors during training this week after getting the call up along with Ospreys second row James King.
Warren Gatland takes charge of his 100th international game tonight as Wales take on Tonga at the Millennium Stadium.
Speaking at a press conference yesterday, assistant coach Rob Howley said Gatland has had a big influence on the performances of both the team and coaches.
The Welsh Rugby Union say they stand 'side by side' with unions in France, Ireland, Scotland and Italy in their intention to continue a full Heineken Cup competition next season.
In statement released late on Thursday evening they said:
"A European club competition is to take place during the 2014/2015 season following an optimised sporting and economic format with 20 teams, no matter how many countries are involved.
"The competition will be driven by the existing organisation (currently named ERC) which will remain in charge of the centralised sale and management of all commercial rights, amongst other things.
"Discussions over governance will be pursued in order to optimise the internal functioning of the existing organisation (currently named ERC).
"The common aim is to move eventually towards the integration of European competitions within an all-encompassing European rugby framework."
The plans though are in direct conflict with the intentions of the umbrella body representing the four Welsh regions, Regional Rugby Wales, who last month made public their desire to join the proposed alternative to the ERC run Heineken Cup, the Rugby Champions Cup.
That competition is also in the sights of English and French clubs who have previously said they will take no part in a continuation of the Heineken which they see as containing unfair distribution of money and unbalanced qualification criteria.
Regional Rugby Wales have made no comment on the matter and there is no indication from the union's joint statement as to which clubs or regions will be taking part.
Wales captain Sam Warburton says players are keen to show their support for former captain Matthew Rees as they prepare to face Argentina tomorrow.
– Sam Warburton, Wales Captain
We spoke as a squad about how to show our support and recognise what Matthew is going through and we felt putting a symbol on the jersey would be a good idea to show we are right behind him.
The idea was a purple smiley face. The purple to represent the testicular cancer charities and the smiley face to represent Matthew as we know him – Smiler.
For me personally he has been a great support in my career and hopefully in a small way this shows how we feel.
The Wales rugby side will wear a special symbol on the sleeves of their jerseys this weekend in support of former captain Matthew Rees, who is battling testicular cancer.
The Cardiff Blues hooker, known as 'Smiler', is taking time away from the game as he undergoes treatment.
The Wales squad, which is gearing up to face Argentina tomorrow, will wear a purple smiley face symbol in recognition of Rees' nickname and testicular cancer charities.
Centre Jonathan Davies and Prop Adam Jones have been ruled out of the rest of Wales' Autumn International campaign, the WRU have confirmed.
Davies left the field during Wales 15-24 loss to South Africa on Saturday after damaging a pectoral muscle during the build up to the Springbok's opening try.
Jones limped out of action in the first half of the same game after damaging a calf muscle.
