Audio of what is believed to be Los Angeles Clippers owner Donald Sterling making racist comments to his girlfriend is being investigated by the NBA.

The man was recorded questioning his girlfriend, V. Stiviano, about her association with black men. According to TMZ, Stiviano, who is black and Mexican, posted a photo of her with Magic Johnson on Instagram, but the picture has been removed.

In the recording, the man believed to be Sterling says: "It bothers me a lot that you want to broadcast that you're associating with black people. Do you have to? You can sleep with (black people). You can bring them in, you can do whatever you want. The little I ask you is not to promote it on that ... and not to bring them to my games."

The NBA released a statement in response to the TMZ report.

"We are in the process of conducting a full investigation into the audio recording obtained by TMZ," spokesman Mike Bass said. "The remarks heard on the recording are disturbing and offensive, but at this time we have no further information."

---Los Angeles Lakers coach Mike D'Antoni recently asked the team to pick up its option on him for the 2015-16 season, reported Saturday.

The two sides had conversations in the past 10 days and the Lakers decided to bring him back for next season, his third with the team, the Orange County Register reported Friday night.

D'Antoni, 62, is reportedly seeking the extension so he does not enter next season with lame-duck status. However, no future meetings have been planned. He is 67-87 since becoming coach.

---Charlotte Bobcats center Al Jefferson said he would play Saturday night's Eastern Conference playoff against the Miami Heat, though his injured left foot still bothers him.

Jefferson took part in Saturday morning's shootaround but said the injury feels "about the same" as it did before Game 2 of their series on Wednesday. According to Bobcats coach Steve Clifford, team physicians said Jefferson cannot injure the foot any worse if he continues to play. However, he said Jefferson would come out of the game if he experiences too much discomfort.

Jefferson had 18 points and 13 rebounds in 40 minutes on Wednesday, despite playing with pain. He sustained the injury during Game 1 of the series last Sunday.
