The New York Knicks have expressed interest again in Kenyon Martin, according to sources.

The Knicks have been conducting due dilligence on Martin in recent days.

Martin is open-minded about signing a 10-day contract with the Knicks.

Rasheed Wallace has missed 12 games due to a foot injury, which has triggered the Knicks' interest in Martin.

Wallace's status is the "critical piece" to the Knicks signing Martin, one league official said.
