As a restricted free agent, David Lee?s future is uncertain and his career as a member of the New York Knicks is in jeopardy.

Mark Bartelstein, Lee?s agent, seemed less than optimistic about a return to New York for his client during an interview with RealGM?s Alex Kennedy on Thursday.

When asked about a return to the Knicks, the team that drafted Lee, Bartelstein hesitated before replying, ?Let?s put it this way, anything is possible but we have interest from other teams as well.?

On Wednesday afternoon, Ken Berger of CBSSports.com reported that Lee had narrowed down his potential suitors to Oklahoma City or Memphis.  

The Grizzlies are out of the running for Lee following their trade for Zach Randolph.

When asked about this, Bartelstein denied the report and said that Lee is still in talks with many teams. ?We have about a dozen teams still showing interest in either signing David or performing a sign-and-trade to acquire him.?

Last season, Lee averaged 16.0 points and 11.7 rebounds for New York while only making $1,788,033.
