Michael Owen says he has "no intention" of leaving Newcastle in January but has refused to commit himself to the club beyond the end of the season.
The 29-year-old is out of contract in the summer and has been linked with moves to Chelsea and Tottenham.
Despite refusing to sign a new three-year contract, the striker insists his decision is "not about money" and he is happy at St James' Park.
"I hope this is seen as a positive, and not disloyal in any way," he said.
"Following speculation about my future at Newcastle United, I have decided to make it clear that I am committed to the club until at least the end of this season, and I have informed them I do not want to make a decision about my future until that time.
I have no intention of leaving Newcastle United during the January transfer window
"I am happy here and enjoy the challenge. It is simply a matter of seriously thinking about my future as I was 29 last week and my next career decision is a crucial one.
"My decision is not about money. I told the club some months ago that I would accept a reduction in my wages.
"I have no intention of leaving Newcastle United during the January transfer window and want to assure the fans that under Joe Kinnear's passionate management, I am committed to ensuring the club ends the season on a high."
Owen has scored 29 goals for Newcastle since joining from Real Madrid for £17m in 2005 and remains a key player, but he has been unable to force his way into England boss Fabio Capello's plans and Newcastle's difficulties on and off the field have not aided his cause.
I am still optimistic that he will stay with us when it comes to making a decision
Magpies boss Joe Kinnear
As he is out of contract at the end of the season, the former Liverpool star will be able to negotiate with other teams about a transfer from January.
While Newcastle fans will be comforted that Owen will be around to try to help them stave off relegation, the speculation over his future - with Manchester City and Everton also linked with the player - is sure now to continue throughout the season.
Kinnear remains optimistic his leading striker, who he said had received a "very good offer", still has a long-term future on Tyneside.
