9:49am: The Heat have officially signed Andersen for the rest of the season, the team announced today (Twitter link).
9:32am: Chris Andersen's second 10-day contract with the Heat is set to expire at midnight tonight, but the Birdman won't be out looking for work tomorrow. According to Benjamin Hochman of the Denver Post (via Twitter), Andersen's agent says his client will be signed for the remainder of the season by the Heat.
Andersen, 34, will be the 15th man on the Heat's roster, meaning the team won't have any open spots remaining. If Miami wants to add another body, the team could always release a player on a guaranteed contract and absorb the extra cap hit. It's also possible that the club opens up a roster spot before the trade deadline by moving a player or two.
After seeing limited minutes during his first 10 days in Miami, Andersen has been worked into the team's rotation during his second contract, averaging 4.3 PPG and 4.3 RPG in four February contests. His rest-of-season contract will be worth a pro-rated portion of the minimum salary, though it's not clear whether or not it will include a team option for next year.
