CLEVELAND, Ohio — J.J. Hickson had just one word — although it was a long one — when he heard the news that Shaquille O’Neal had announced his retirement on Wednesday afternoon.

“Nooooooooo!!!!” Hickson tweeted in tribute to his former teammate.

Daniel Gibson’s Twitter response was the same word but three times that long and concluded with, “Say it ain’t so Big Homie! Say it ain’t so!”

O’Neal, 39, announced his retirement on the new social media tool Tout, a real-time video messaging service: “We did it. Nineteen years baby. I want to thank you very much, that’s why I’m telling you first, I’m about to retire. Love you, talk to you soon.”

A four-time champion, 15-time All-Star and three-time NBA Finals MVP who was the 2000 NBA MVP and the 1993 Rookie of the Year, O’Neal is fifth on the all-time scoring list with 28,596 points. According to ESPN, he is the only player to average at least 20 points and 10 rebounds per game for 13 seasons.

“Shaq is one of the NBA’s all-time great players and ambassadors,” said Cavs General Manager Chris Grant. “He will truly be missed for not only all he accomplished on the court but also the impact he made in every community in which he played.”

O’Neal, who spent this past season with the Boston Celtics, spent just one season with the Cavaliers — 2009-10 — which ended not as he or his teammates had hoped. The Cavs finished the regular season with a league-best 61-21 record, but lost to the Celtics in six games in the Eastern Conference semifinals, leaving O’Neal far short of the fifth championship ring he sought.

Limited to 53 regular-season games because of injuries, O’Neal averaged just 12 points and 6.7 rebounds in the regular season and 11.5 points and 5.5 rebounds in 11 playoff games.

Obtained by the Cavs on June 25, 2009 from Phoenix in exchange for Ben Wallace, Sasha Pavlovic, a second-round pick in 2010 and cash, O’Neal did a masterful job of toning down his big personality in order to fit into a team he clearly saw as LeBron James’.

From Miami, James tweeted, “What a career for Shaq Diesel!! The most dominating force to ever play the game. Great person to be around as well. Comedy all the time!! He will be missed!!”

O’Neal has called a press conference for Friday at his home in Isleworth, Fla., outside Orlando, but he told ESPNBoston.com’s Jackie MacMullan that a persistent and painful Achilles injury led to his decision. He told MacMullan he had more than five cortisone shots, over the objections of team physician Brian McKeon, in order to try and play against the Miami Heat in the second round of the playoffs last month.

O’Neal said he rejected the notion of surgery, which could require up to nine months to recover, virtually wiping out the second year of his contract with the Celtics.

“I didn’t want to let people down two years in a row,” he told MacMullan. “I didn’t want to hold Boston hostage again.”

As great as his basketball career was, O’Neal also built a second career in entertainment, including music, movies, television shows and commercials, and he also was active in community service and charity work, much of which went unpublicized.

“I tried to make people happy,” he told MacMullan, “and I tried to have fun. I think I did both.”

It looks like former Cleveland Cavaliers coach Mike Brown will become the new coach of the Los Angeles Lakers.

Brad Turner of The LA Times reports the Lakers have put together a deal worth between $4 million and $4.5 million per season, for three years, with a team option on the fourth season that would give him partial pay if he was not retained.

Brown, 41, became the front-runner because Jim Buss, the team’s executive vice president of player personnel, was impressed with his defense-minded style.

Lakers owner Jerry Buss did an interview with Sirius XM Radio on Tuesday, saying the team was “very close” to filling its coaching vacancy.

It now appears as if Brown is that person, something that could be announced in the next 24 to 48 hours.

Brown left the Cavaliers after five seasons with a 272-138 record. After the Cavaliers lost to the Boston Celtics in the conference semifinals in 2010, Brown was fired.

The Lakers have put together a deal to hire former Cleveland Cavaliers coach Mike Brown as their new coach, an NBA official who was not authorized to speak publicly on the matter said late Tuesday.

If Brown agrees to the deal, he’ll sign a contract worth between $4 million and $4.5 million per season, the official said. Brown would sign for three years, with a team option on the fourth season that would give him partial pay if he was not retained.

Brown, 41, became the front-runner because Jim Buss, the team’s executive vice president of player personnel, was impressed with his defense-minded style.

Former Houston Rockets coach Rick Adelman also was in the mix for the job and will remain a candidate to replace Phil Jackson if Brown turns down the deal from the Lakers.

Lakers assistant coach Brian Shaw also was considered for the head position.

The Lakers had to wait until General Manager Mitch Kupchak and Buss returned from pre-draft camps in Chicago and Minneapolis on Tuesday night before they could get a deal done.

Lakers owner Jerry Buss did an interview with Sirius XM Radio on Tuesday, saying the team was “very close” to filling its coaching vacancy.

It now appears as if Brown is that person, something that could be announced in the next 24 to 48 hours.

Brown was with the Cavaliers for five seasons until he was fired in 2010, leaving with a 272-138 record.

He was named the NBA’s coach of the year in 2009 for leading the Cavaliers to a 66-16 record.

Brown led the Cavaliers to a 61-21 record during the 2009-10 season, another league-best record.

But after the Cavaliers lost to the Orlando Magic in the 2009 Eastern Conference finals and to the Boston Celtics in the conference semifinals in 2010, Brown was fired.

Brown led the Cavaliers to the NBA Finals in 2007, but Cleveland was swept by the San Antonio Spurs.

Brown coached one of the NBA’s superstars in former Cavalier LeBron James.

In his radio interview Tuesday, Jerry Buss said that he expected the Lakers’ core roster to return next season, with a “tweak … here or there.”

Buss was interviewed by Playboy Radio’s Michael Eaves and Bonnie-Jill Laflin.

Buss did say there would be changes in the Lakers’ offense.

“We’re not going to continue exclusively with the triangle,” Buss said. “Certainly, there will be facets of the triangle incorporated into any modern offense.”

Various Lakers, including Kobe Bryant, Derek Fisher and Luke Walton, have publicly endorsed Shaw to be the next coach, in part because of his familiarity with their personnel.

The Los Angeles Lakers are looking at former Cleveland Cavaliers coach Mike Brown as a possible successor to retired coach Phil Jackson, according to ESPN.com.

The Los Angeles Lakers are taking a deliberate approach to their search for a successor to Phil Jackson, but NBA coaching sources told ESPN.com the team has added Mike Brown to its list of candidates.

The former Cleveland Cavaliers coach, now working as an analyst for ESPN, is expected to interview “soon” with the Lakers, sources say.

Brown would become the fourth known candidate for the job, along with former Houston Rockets coach Rick Adelman, ex-Los Angeles Clippers coach Mike Dunleavy and Lakers assistant coach Brian Shaw, who is regarded as the only serious in-house contender to replace Jackson.

The site says that Brown is considered a leading candidate for the head coaching vacancy at Golden State. Indiana Pacers President Larry Bird said he’s among those being considered for that job, as well.

Brown was dumped by the Cavaliers shortly after the team built around LeBron James fell to the Boston Celtics in the 2010 playoffs. James left the Cavs last summer in a televised special called “The Decision” and “took his talents to South Beach.” James, Dwyane Wade and Chris Bosh decided that together, they could win multiple NBA titles with the Miami Heat.

As of now, the Heat and Chicago Bulls are tied 1-1- in their playoff series.
