Nuggets' Martin out

DENVER -- Nuggets forward Kenyon Martin will not play against the Mavericks due to chronic discomfort in his left knee.

Martin has been dealing with tendonitis in his left knee patella and might rest through the All-Star break.

The Dallas native is the Nuggets' best defender, drawing the assignment on Dirk Nowitzki. Denver coach George Karl compared his absence to a football team losing its middle linebacker.

Malik Allen, who had a brief stint with the Mavericks, will start in Martin's place.
