Injury-plagued defender Jonathan Woodgate could play his last match for Tottenham against Birmingham.
Spurs boss Harry Redknapp said he does not know whether the club will offer the England international a new contract this summer.
Woodgate, an £8m signing from Middlesbrough in 2008, has suffered a succession of injuries which have restricted his appearances for Spurs.
"His contract is up and he hasn't played for two years," said Redknapp.
A career-threatening groin injury kept Woodgate out for 15 months at the end of 2009 but he made a long-awaited return in Tottenham's stunning 1-0 away victory against AC Milan in the Champions League last-16 match in February.
However, the 31-year-old suffered another groin injury at the San Siro, further compounding his frustrations on the sidelines, and has missed every match since.
Woodgate has been included in Tottenham's provisional squad to face Birmingham on Sunday and, if he plays, it would only be his fifth appearance in two seasons.
While Redknapp conceded he could let Woodgate go this summer, he also said any manager who took a gamble on the former Real Madrid player would be richly rewarded should he return to full fitness.
"If we don't keep him then he is worth a gamble for someone on a pay-as-you-play deal because if you can get him fit you will have one of the best centre-halves anywhere," he said.
"If I wasn't at Tottenham I would take a gamble on him. He could be a fantastic signing because he is training this morning [Friday] and he feels fit for the first time in two years."
While Redknapp ponders whether Woodgate will figure in his future plans, midfielders Jamie O'Hara and David Bentley and forwards Giovani Dos Santos and Robbie Keane look set for summer exits from White Hart Lane having spent large parts of the season on loan.
Jermain Defoe has said he has been frustrated by his limited Premier League appearances this season, fuelling speculation the striker will be leaving Spurs this summer.
And Redknapp confirmed he will meet Tottenham chairman Daniel Levy next week to finalise his plans for next season, including potential summer transfer targets.
"If we have one or two definite targets then we will [move for them early] but we also have one or two who may take their time to move on," he said.
"It's not easy to sell players. We have players who would do well for people but someone's got to want to buy them first and that's not always easy."
One player unlikely to join the club is Manchester City striker Emmanuel Adebayor, whose wage demands would break the club's payments structure.
"The top Champions League teams are earning crazy money so it's difficult to sign players," added Redknapp.
"We don't pay the wages that Chelsea do and quite rightly so. Daniel doesn't want to put this club at risk to play those sorts of wages. It's a very well run club here.
"It works within its means and he runs it how it should be. If players wanted £180,000 a week then they are not going to get it at Tottenham, no more than they are going to get it at Aston Villa or too many other clubs."
