David Stern is stepping down in February 2014 as NBA commissioner after a 30-year run.
The NBA announced the move Thursday at its Board of Governors meeting in New York.
Replacing Stern will be deputy commissioner Adam Silver, who will work with the outgoing commissioner during the transition.
The Board of Governors unanimously approved the move, chairman Glen Taylor announced. Formal approval of Silver, who worked with the league for 20 years, will come in April.
Stern, 70, took the job on Feb. 1, 1984, and served in the commissioner's role longer than any of his predecessors. His official retirement date will be Feb. 1, 2014.
Stern will remain involved with the league as a consultant after his retirement.
--The foot injury that prompted the Los Angeles Lakers to shut down Kobe Bryant for the remainder of the preseason might result in him missing Tuesday's season opener.
Bryant sat out Wednesday's exhibition game against the Los Angeles Clippers and won't play Thursday night against the Sacramento Kings. The Lakers open the regular season Tuesday against the Dallas Mavericks.
"I don't know if he'll be ready," Lakers coach Mike Brown said. "So yeah, I guess there is question. I'm just going to wait for (trainer) Gary Vitti to tell me he can play because there's nothing I can do about it until they release him anyway."
ESPN.com reported that Bryant felt some improvement in his strained foot. The 17-year veteran received treatment during Wednesday's game and didn't join his teammates on the bench. Bryant suffered the injury, which is causing him significant pain, on Sunday night in a game against the Kings.

"If I'm not what u lookin 4 ... That's fine. ... just dont kick me in my -- on the way out the door. ... I didn't do anything to deserve that. ..."
A subsequent post said, "I love the city of Dallas ... I love playin in the NBA. ... no I'm not off my meds. ... no I ain't on no bipolar trip. ... this real people lives.."
West has said he suffers from bipolar disorder and takes medication.
--The sale of the Memphis Grizzlies to a group headed by 34-year-old billionaire Robert Pera was unanimously approved by the NBA Board of Governors meeting in New York.

Pera, who founded wireless-company Ubiquiti Networks, and his investor group reportedly paid around $350 million to outgoing owner Michael Heisley for the Grizzlies.
Minority owners in Pera's group are reported to be entertainer Justin Timberlake, football star Peyton Manning and his wife, and former NBA player Penny Hardaway.
