Wales team coach Warren Gatland admitted that a training session had been cancelled so that players could continue negotiations but insisted he was "confident" that the match would go ahead.

"I'm hearing positive things from both sides," said Gatland.

"Hopefully the discussions will be acceptable to both sides in terms of getting some compromise and we can get on with the game.”

Players in the Welsh squad have set tomorrow as a deadline for certain conditions relating to contracts to be resolved or they could decide not to play the international match.

Welsh Rugby Player Association (WRPA) chairman Ashton Hewitt has warned any action could spread throughout Wales if agreement has not been reached.

He warned "striking for every player in Wales," had become a "definite" possibility.

The WRPA has been in talks with the Professional Rugby Board (PRB) which represents the Welsh Rugby Union and the four major club sides - Cardiff Rugby, Scarlets, Ospreys and Dragons since January.

The dispute centres on future pay structures.

The PRB had insisted that "clubs have been paying salaries that their businesses cannot afford."

It is understood that the PRB have offered a deal in which 80 per cent of salaries are guaranteed with the remaining 20 per cent linked to win bonuses and other payments.

They claim that the deal would mean a salary of £100,000 ($121,200/€113,600) per player.

The WRPA has complained that there has been insufficient time to study proposals which are understood to form the basis of a deal to run for the next six years.

"We've had the detail very late, we haven't been consulted on it well enough," Hewitt admitted.

"I have a lot of fear… a lot of the boys have issues on the table and we don't know if things are going to be resolved."

Cardiff Rugby’s back row forward  Josh Turnbull has also described the situation as “vulnerable and uncertain" and had caused "severe stress."

Turnbull insisted the PRB had "shown a lack of empathy and respect towards players."
