Toulon and Wales fly-half Leigh Halfpenny plans to make a decision on his future "in the next month or so".
Halfpenny's contract with the Top 14 giants expires at the end of this season and the British and Irish Lion has been linked with a return to Cardiff Blues, as well as ambitious Wasps.
The Welsh Rugby Union (WRU) last month announced that only three players who ply their trade outside their homeland can be selected for an international season, so Halfpenny would need a wildcard pick to play for his country if he stays in France.
Halfpenny, whose current deal does not restrict his availability to play for his country, has not made his mind up over whether to remain with the three-time European champions or move on next year.
"For the time being I haven't put much thought into it but I know that decision will be coming in the next month or so," he told BBC Wales Sport.
"At the moment, I'm in my last year of contract in Toulon and, for me, at this moment in time I'm just fully focused on being back playing, getting over that injury and not thinking about anything other than playing and putting in performances for Toulon and Wales."
The 27-year-old added: "If selected [for Wales], I didn't want to miss out on any training or matches,
"Having that full release in the contract allows me to play for my club during club time and, if selected, for Wales, which I love doing. It's the best of both worlds.
"I signed the contract before the law was in place and I also negotiated full release for every training camp and every game."
