Vinny Del Negro will return as head coach of the Clippers for the 12-13 season.

The Clippers held an option on Del Negro's contract.

Mike Woodson has been given a multi-year contract extension by the Knicks. 

Frank Isola of the New York Daily News reports that the deal is for three years.

“Mike took over the team under challenging circumstances and made it clear, starting on day one, that he was going to hold every player on our roster accountable,” said James Dolan, Executive Chairman, The Madison Square Garden Company. “We saw a significant improvement since Mike took over and believe our team will only keep improving under Mike’s direction.”

Woodson, who had served as New York’s interim head coach since Mar. 14, 2012, guided the Knicks to an 18-6 regular-season mark and the franchise’s second consecutive playoff berth. Over the last 24 games of the regular season, the Knicks posted the second-best record in the NBA and the team’s defense ranked fifth in the NBA in points allowed (91.8) and eighth in opponents’ field goal percentage (.440). Woodson became the first head coach in franchise history to win his first five games and posted the second-best winning percentage ever by an NBA coach who took over a team midseason.

“Mike has the respect of every person in this organization,” Executive Vice President, Basketball Operations and General Manager Glen Grunwald said. “He and his staff led the team in an impressive push into the playoffs over the last 24 games and we believe he is the right man to lead the franchise as we move forward.”

Stan Van Gundy has been relieved of his duties as head coach of the Magic, while President of Basketball Operations and General Manager Otis Smith and the organization have mutually agreed to part ways.

"On behalf of the DeVos Family, we sincerely appreciate and thank Otis and Stan for all that they have done on and off the floor for the Orlando Magic,” said Martins. "These are the days you dread in this business, but we feel it's time for new leadership and new voices."

Van Gundy was named head coach in June of 2007. Van Gundy has a career NBA head coaching regular season record of 371-208 (.641), including 259-135 (.657) in five seasons in Orlando.

Smith was named general manager on May 3, 2006. He was assistant general manager during the 2005-06 campaign, after serving as director of player development for two seasons.

The Bulls will pick up their option on Tom Thibodeau's contract for the 12-13 NBA season.

The two sides will also begin extension discussions this summer.

"Obviously, we value Tom greatly," GM Gar Forman said. "We value what he brings to the organization and what he brings to the team and think he's one of the finest coaches in the league and we're hopeful he'll be our coach long-term.

Thibodeau said an extension is not foremost on his mind.

"I'm not worried about that," he said. "Those things take care of themselves."

Carlisle has a .635 winning percentage with the Mavericks.
