BOSTON (AP/WFAN) — Shaquille O’Neal, who struggled to get on the court for the Boston Celtics because of leg injuries, said on Twitter on Wednesday that he is going to retire after a 19-year career in which he won four NBA titles and the 2000 league Most Valuable Player award.

O’Neal sent a tweet shortly before 2:45 p.m. saying, “im retiring.” It included a link to a 16-second video in which he says, “We did it; 19 years, baby. Thank you very much. That’s why I’m telling you first: I’m about to retire. Love you. Talk to you soon.”

An inveterate pranskter, originally from Newark, New Jersey,  gave himself a new nickname — or several — in each of his six NBA cities, the Big Shamroq did not notify his latest team of his plans. He played just 37 games this year, the first of a two-year deal at the veteran’s minimum salary, making just three brief appearances after Feb. 1.

“To my knowledge, he has not informed any of us that he’s retiring,” Celtics spokesman Jeff Twiss said.
