NBA Commissioner David Stern said Friday the league is extending until May 2 the deadline for the Kings to request a move to Southern California.

Sacramento is trying to save the Kings with a new arena plan.

Stern said other NBA owners still have an "incomplete" understanding of the Anaheim deal, which he said has changed within the past few days. 

"It was sort of like a timeout, this is difficult, let's take some time here to better understand it," Stern said. He later added the Honda Center, where the Kings would play, needs "substantial" upgrades to support the NBA.

Anaheim officials professed not to be bothered by the delay.

"We are very excited and confident that as they learn about Honda Center, they will see the virtues of a team in Anaheim," said Michael Schulman, chairman of the firm that runs the arena.
