Chris "The Birdman" Andersen is back in the NBA.

Well, at least for the next 10 days with the Miami Heat, along with Jarvis Varnado, who also signed a 10-day contract with the defending NBA champions.

From Ethan J. Skolnick of The Palm Beach Post:

Miami has signed Jarvis Varnado and Chris Andersen to 10-day contracts, according to team. Andersen has been in Miami working out.

Andersen may be most known for his colorful personality and appearance, but the hope will be that he can bring rebounding and shot-blocking off the bench for the Heat, who desperately need help in the rebounding department.

The Heat are currently tied for last in the NBA with 38.8 rebounds per game.

Andersen last played for the Denver Nuggets during the 2011-12 season, but he was cut midseason after appearing in 32 games for the team.

After being waived by the Boston Celtics this season, Varnado is now on his second consecutive 10-day contract with the Heat. He's made two appearances for the team and played all of 12 minutes, with two blocks and two points in those appearances.

While these moves are hardly earth-shattering for the Heat, as it's a long shot either player will see significant minutes, the addition of Andersen is an intriguing one for NBA fans on several levels. He's always been a fan favorite, and his energy off the bench could provide a spark for the Heat.

The veteran also plays good defense and should bolster the Heat's rebounding if he can replicate his level of play from several years ago. If the Heat can eventually get 15 minutes and five rebounds per game from Andersen, he'll be well worth this initial 10-day offer.
