Shaquille O'Neal had more than 28,000 points and almost 4 million Twitter followers. He appeared in six NBA finals, three times as the MVP, and seven feature films, twice in a starring role.

A 15-time All-Star, four-time champion and the 2000 NBA Most Valuable Player, the 39-year-old O'Neal announced his retirement on Twitter on Wednesday after spending most of his 19th season on the Boston Celtics bench, in street clothes because of leg injuries.

Along with a mid-afternoon tweet saying, "im retiring," O'Neal included a link to a 16-second video of him saying, "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 prankster who gave himself a new nickname - or several - in each of his six NBA cities, O'Neal did not notify his latest team, leaving it wondering about his plans. He played just 37 games this season, the first of a two-year deal at the veteran's minimum salary, making just three brief appearances after Feb. 1.

"For 19 seasons, Shaquille O'Neal was literally and figuratively an NBA giant," commissioner David Stern said in a statement. "On behalf of the NBA, its teams, and his millions of fans around the world, I want to thank Shaq for everything he has meant to the league and to the sport of basketball, both on and off the court. We wish him and his family all the best."

O'Neal, 39, retires fifth all-time with 28,596 points, 12th with 13,099 rebounds, and a .582 field goal percentage that is second only to Artis Gilmore among players with more than 2,000 baskets. His free throw percentage of .527 - well, now is not the time to dwell on that.
