A purported conversation between Sterling and his girlfriend V. Stiviano was released on Friday, in which he said he didn't want Stiviano taking photos with black people or bringing blacks to his basketball games.
Newly appointed NBA commissioner Adam Silver previously said he would wait to see the results of an internal league investigation before announcing any punitive measures upon Sterling.
"All members of the NBA family should be afforded due process and a fair opportunity to present their side of any controversy," Silver said, according to ESPN. "The core of the investigation is understanding whether the tape is authentic, interviewing Mr. Sterling and interviewing the woman as well and understanding the context in which it was recorded."
The team's players staged a silent protest at center court before they took on the Golden State Warriors in Sunday's Game 4 of their first-round series.
