Shaquille O'Neal has confirmed to the Orlando Sentinel that he won't sign another NBA contract.

O'Neal plans to retire as a member of the Celtics, meaning his legendary career has just two seasons left after he inked a two-year deal with Boston earlier this summer.

"I'm not coming in to take over," O'Neal said. "At this point in my career I'm just a role player and I'll do whatever it takes [to win]."
