Toulon prop Gethin Jenkins has not given up hope on playing in Wales' autumn test finale against Australia.
France-based quartet Jenkins, James Hook, Luke Charteris and Mike Phillips are unavailable for Wales' pre-autumn training camp in Poland, starting next weekend, because of Top 14 club commitments. It is also highly unlikely they will make the Australia clash on December 1 as that game falls outside the International Rugby Board fixture window and clubs are not obliged to release their players.
"I don't think I am going to Poland," Jenkins said. "I will be back (with Wales) after our Stade Francais game, which is on November 1."
But in terms of the Wallabies fixture, Jenkins added: "We will wait and see, fingers crossed.
"There are ongoing talks, and we will see what happens when it comes to that situation."
Wales interim head coach Rob Howley accepts that a solution to Welsh international rugby's overseas player departures will not be found overnight. But Howley is confident discussions between the Welsh Rugby Union and four professional regions - Cardiff Blues, Scarlets, Ospreys and Newport Gwent Dragons - can reach a satisfactory conclusion.
"Warren (Gatland) and myself went over to France and had five or six days with the various coaching teams in Bayonne, Toulon and Perpignan," Howley said.
"There are ongoing discussions with those players based in France. At this moment in time, those players are unlikely to be involved in the Australia game.
"But it is important we look at every individual case and why that player is going to France.
"If they are being head-hunted, then surely between the agent, the player and the club president there can be some sort of arrangement or discussion that the player becomes available for some preparation time or a game outside the IRB Test window."
