Highly sought-after unrestricted free agent big man Marcus Camby postponed his meeting with the Miami Heat on Saturday, according to a source with knowledge of his plans.

It was done to allow the team to work on a potential sign-and-trade with the Houston Rockets, but the Rockets aren't currently interested in dealing with the Heat.

The Rockets, according to sources, are more interested in a sign-and-trade with the New York Knicks. Sources told ESPN.com that the Knicks have had discussions with the Rockets about Camby, as well as the Dallas Mavericks about a sign-and-trade for free agent Jason Kidd, who agreed to join the Knicks earlier this week.

The Knicks are hoping to make a sign-and-trade deal for one of them and use their $3.09 million mid-level exception to sign the other.

A source close to Camby would be "shocked" if he signs anywhere for the veteran's minimum of $1.4 million, which is what the Heat only have available after Ray Allen agreed to their mid-level exception of $3.09 million on Friday.

That financial factor is one of the biggest reasons why the Knicks have the edge over the Heat and are the early favorite to land Camby, who is meeting with the team's front office on Sunday in Houston. That's where the 38-year-old played toward the end of last season after being traded from Portland.

In addition to the opportunity for a higher salary, a source close to Camby said the center is drawn to the Knicks because he has a "great relationship" with general manager Glen Grunwald. He was the assistant general manager in Toronto in 1996 when the Raptors made the center the second pick in that year's NBA draft.
