Warren Gatland hopes “common sense” will prevail and allow Wales to play the ineligible British and Irish Lions scrum-half Rhys Webb at the 2019 Rugby World Cup.
Webb is unable to represent Wales following his move from the Ospreys to Toulon as Welsh Rugby Union rules stipulate that players based outside the country must have 60 caps.
The 29-year-old has 31 caps and WRU chief executive Martyn Phillips said last week that the rules will remain in place for the foreseeable future as doing otherwise gives people “false hope”.
But Wales coach Gatland has not given up hope of having Webb in his World Cup squad in Japan 12 months from now.
“The rules say that I can’t, but if there are a couple of injuries I would like to think – say we lost two of our three nines that we have at the moment – then there would maybe some common sense.
“I don’t think anyone wants to see a team hampered by the ability to be able to pick the best player.
“We do have regulations at the moment which have been agreed by the Union and the regions, not so much the coaches. They would be more flexible.”
Webb missed the 2015 World Cup after suffering a serious foot injury in the final warm-up game against Italy.
Webb announced last October he was moving to France for three years, and Top 14 club Toulon said the agreement allowed him to continue playing for Wales.
But Webb fell foul of new WRU regulations which come into force this month and are designed to encourage the best Welsh players to remain home-based.
“I do feel sorry for him as he had agreed terms with Toulon before the policy had taken place,” Gatland said.
“That’s tough. Would he have still made the decision? I don’t know.
“But there is a part of me that still thinks he would have made the decision to go anyway.”
Wales took Scarlets pair Gareth Davies and Aled Davies and Cardiff Blues scrum-half Tomos Williams on their summer tour to the United States and Argentina.
The trio did well in the victory against South Africa in Washington DC and the 2-0 series win in Argentina, but Gatland remains a huge fan of Webb.
“There is no doubt that when Rhys is fit and playing well he is world class,” Gatland said.
“If he is playing well, his form is good enough, seeing what happens with their other nine, is there a possibility (he could play at the World Cup)?
“At the moment it is a firm no, but you can never say never.
“If we turned up in nine months and it was important to us to take Rhys, would people consider an exception?
“But let the dust settle on it and when we get closer let’s see if it might be a possibility.”
