Nuggets forward Kenyon Martin may not return this season as he deals with a left knee injury.

Martin has described his chances of playing in any of Denver's remaining seven regular-season games as "dim."

He missed his 14th consecutive game when the Nuggets lost to the Mavericks on Monday night. He has been undergoing platelet-rich plasma therapy, which involves injecting his blood into his knee to help spur tendon recovery.

"Realistically, I might not be able to play this year. ... I might not be able to play the rest of the year," Martin told Yahoo! Sports. "That's what I'm realistic about, that I might not be able to. It's still up in the air. But, I'm going to do all I can to make sure. I'm going to put my best foot forward and work hard every day to make sure I get back, but if it's not meant to be, then it's out of my control.

"Nobody will ever be upset that I didn't try. They will never be able to say that. I've fought through stuff worse than that."

The team's medical staff diagnosed Martin with a partial tear of his left patella tendon on March 5, with surgery among the possible options, according to sources.

Denver has publicly referred to the injury as "patella tendonitis."
