SAN FRANCISCO — Anger, frustration and calls for action echoed around the NBA on Saturday after an audio recording surfaced of a man identified as Los Angeles Clippers owner Donald Sterling telling his girlfriend not to bring black people to games.

Everybody except for the embattled Clippers owner, who has a decades-long history of alleged discrimination and offensive behavior, seemed to have a response.

The league said it was investigating the recording posted on TMZ's website, calling the comments "disturbing and offensive." Lakers Hall of Famer Magic Johnson, a target of Sterling's remarks, said he wouldn't attend Clippers' games as long as Sterling was the owner. Miami Heat star LeBron James asked new NBA Commissioner Adam Silver to take aggressive measures, saying "there is no room for Donald Sterling in our league."

"Obviously, if the reports are true it's unacceptable in our league," James said. "It doesn't matter, white, black or Hispanic — all across the races it's unacceptable. As the commissioner of our league they have to make a stand. They have to be very aggressive with it. I don't know what it will be, but we can't have that in our league."

Silver spoke Saturday night in Memphis, Tenn., before the Grizzlies' game against Oklahoma City, repeating that the league finds the audio tape "disturbing and offensive" and that Sterling agreed to not attend the Clippers' game Sunday at Golden State.

"All members of the NBA family should be afforded due process and a fair opportunity to present their side of any controversy, which is why I'm not yet prepared to discuss any potential sanctions against Donald Sterling," Silver said. "We will, however, move extraordinarily quickly in our investigation."

Silver said the NBA needs to confirm authenticity of the audio tape and interview both Sterling and the woman in the recording. The Clippers will be back in Los Angeles for Game 5 on Tuesday night.

"We do hope to have this wrapped up in the next few days," Silver said.

Clippers coach Doc Rivers said players discussed boycotting Game 4 of their first-round playoff series during a 45-minute team meeting but quickly decided against it.

"I think the biggest statement we can make as men, not as black men, as men, is to stick together and show how strong we are as a group," Rivers said. "Not splinter. Not walk. It's easy to protest. The protest will be in our play."

Clippers President Andy Roeser said in a statement that the team did not know if the tape is legitimate or has been altered. He said the woman on the tape, identified by TMZ as V. Stiviano, "is the defendant in a lawsuit brought by the Sterling family alleging that she embezzled more than $1.8 million, who told Mr. Sterling that she would 'get even.'"

Roeser also said the recording does not reflect Sterling's beliefs. He added that Sterling is "upset and apologizes for sentiments attributed to him" about Johnson, whom he called Sterling's friend.

In the recording posted on TMZ, the man questions his girlfriend's association with minorities. TMZ reported Stiviano, who is of black and Mexican descent, posted a picture of herself with Johnson on Instagram — which has since been removed.
