Shawn Marion will not be opting out of his contact with the Miami Heat for next season, but the two sides could not agree on a contract extension, which may see Marion become an unrestricted free agent after next season, according to a report on ESPN.

"I spoke to Shawn again tonight, and we've decided that he's not going to opt out," agent Dan Fegan said. "It just wasn't in Shawn's best interest. That's all I can really say about it right now."
