The Miami Heat's search for rebounding and size has led to one new face and the return of a prospect.

Returning to practice Sunday at AmericanAirlines Arena for the first time since their rebounding issues again were exposed on their just-completed six-game trip, the Heat shook up their power rotation by signing veteran center Chris Andersen and re-signing rookie power forward Jarvis Varnado.

Because of the moves, center Josh Harrellson was not retained after his 10-day contract expired. Also, the Heat announced that center Dexter Pittman again has been recalled from the NBA Development League.

The focus Sunday, though, was on Andersen.

"It's a great fit for me," Andersen said of being called in to provide rebounding and defense. "It's what I do."

Andersen, known for his colorful tattoos, Mohawk haircut and headband summed up his personality after Sunday's workout.

"Let's say I'm a colorful guy," he said. He added, "I'm a good-old country boy that likes to get the job done."

Asked what he would bring to the Heat, he said, "The usual that a Birdman does and what Birdman brings."

Among the reasons Andersen, 34, had remained unsigned was an uneven NBA tenure that has included being banned by the league for two years in 2006 for violating the league's substance abuse program. Then, in May, Denver news outlets reported that Andersen's home was the target of an investigation of a suspected internet case by the Douglas County Sheriff's Office Internet Crimes Against Children Unit. No charges have been filed, with his representatives classifying it as an extortion attempt by a woman portraying herself of being of legal age.
