Greg Oden has no intention of calling it quits, according to a source close to the situation.

"It's hard to put into words the heartbreak for everyone involved, but especially for Greg," said Blazers president Larry Miller. "He's a young man who has experienced a great number of physical challenges in his playing career and today is yet another significant setback for him. We have a lot of empathy for Greg and his family during this difficult time."

Oden has appeared in just 82 games over the last five seasons.

"Greg's still very young, in relative terms, for a professional basketball player," acting GM Chad Buchanan told reporters. "He's recovered from a couple of these before. His last two microfracture lesions have healed fine. So there's no reason to think he couldn't come back as long as he shows the work ethic and desire that he's had in the past to come back. I think it's premature to speculate anything beyond that."
