Shaq won't be back!

After 19 seasons of playing in the NBA, Shaquille O'Neal is ready to throw in the towel.

"We did it. 19 years baby. I want to thank you very much," he said in a video posted Twitter on Wednesday. "That's why I'm telling YOU I'm about to retire. Love you. Talk to you soon."

The 39-year-old has played for six pro teams -- Orlando Magic, the L.A. Lakers, Miami Heat, Cleveland Cavaliers, Phoenix Suns and Boston Celtics. In addition to his pro career, O'Neal has released four rap albums and starred in his own reality shows, Shaq's Big Challenge and Shaq Vs. In 2005, he was officially sworn in as a Miami Beach police officer.

O'Neal is currently the oldest active player in the NBA.
