Yahoo! Sports is reporting that Chris "Birdman" Andersen will test the free agent market.
Marc J. Spears reports that Andersen will opt out of the final year of his contract.
Andersen, 35, was a key spark for the Heat's 2013 championship and remains a fan favorite.
Andersen could be looking over his options with uncertainty existing for the futures of LeBron James, Chris Bosh and Dwyane Wade.
The Spurs eliminated the Heat on Sunday night.
It was Miami's first playoff series loss since 2011.
