Mark Taylor fears his Test career might be ended by the tussle for his services between Wales and his club Sale. The centre, 32, withdrew from Wales' injury-ravaged squad to face South Africa and Australia due to a holding clause in his Sale contract.
"It's a very difficult time for me," Taylor told BBC Wales Sport.
"I'd like to think I've got more games for Wales ahead of me, but in the back of my mind is the idea that I might have played my last game."
Wales are in discussions with the International Rugby Board, the sport's world governing body, over the situation.
IRB rules are clear that a club must release a player once he is called up for duty on an official international match date, unless he is injured.
Should a player not be released for an international match, he is then banned from playing for his club side during that period.
But Taylor, who has won 52 caps, is hoping that the situation can be resolved with English club side Sale before it is taken any further.
"It's a very tough time for me that I need to discuss with a number of people, and I need to do it sooner rather than later so that everyone knows where they stand," Taylor added.
"It's being talked about and as soon as I know where I'm going with that I'll let everyone know as well.
"Hopefully it'll be resolved this week, I need to sit down with our owner (Sale Sharks benefactor Brian Kennedy) and find out exactly where he needs me to be during the Six Nations.
"I can take it from there, because Mike Ruddock as Wales coach needs to know whether I'm available to be selected or not."
