The Miami Heat, San Antonio Spurs, Los Angeles Clippers, Atlanta Hawks and New York Knicks are pursuing free-agent forward Kenyon Martin, according to league sources. Martin has spoken with executives from each of the clubs and is hoping to make his decision next week. The veteran of 11 NBA seasons will be eligible to sign and begin playing with a team as soon as the Xinjiang Guanghui Flying Tigers complete their season in the Chinese Basketball Association.

The FIBA season ends February 16th.

Martin's priority is to join a contender on which he'll have a sizeable role, according to a person close to Martin.

This is a new twist on the annual "buy-out watch" isn't it? I don't really know what Kenyon has left to offer a contender but with all the power forwards on our roster, I don't think the Celtics are a great fit anyway.
