Craig Bellamy says fitness issues means he cannot commit to playing for Wales.
The 33-year-old striker, capped 70 times, missed Wales' last four 2014 World Cup qualifiers because of injury.
Wales manager Chris Coleman has urged Bellamy to say whether he still wants to be involved in the squad, but Bellamy remains noncommittal.
"If I have something to offer the team, I'll have a serious look at it," said Bellamy on a possible Wales return.
"But that's a number of weeks away, I do concentrate week by week. I have Ipswich [with Cardiff on Saturday] and the honest truth is I don't even know if I'm playing next week.
"There's no point looking further than that. Ipswich is the main target and we'll just have to push on from there."
