ESPN analyst Keith Olbermann is calling on L.A. Clippers players to boycott the team's remaining NBA playoff games in the wake of a tape surfacing where a man reported to be team owner Donald Sterling sternly instructs a woman "not to bring black people to my games."

Taking to Twitter early Saturday morning, Olbermann posted "time for Clippers players to step up. Refuse to play till NBA moves against this racist jackass. NBA can't defend him."

According to TMZ Sports, the tape in question was published April 9 and reveals Sterling arguing with a racially-mixed, black and Mexican woman since identified as his girlfriend about taking photos with NBA legend Magic Johnson and posting them to her Instagram page.

"It bothers me a lot that you want to broadcast that you're associating with back people," Sterling reportedly shouts. "Do you have to? The little I ask you is not to promote it on that ... and not to bring them to my games. I'm just saying, in your lousy f******* Instagrams, you don't have to have yourself with, walking with black people. Don't put him on an Instagram for the world to have to see so they have to call me. And don't bring him to my games."

The picture of Johnson has since been removed from V.Stiviano's page, but Sterling's history of racist behavior remains well documented. The NBA owner and real estate magnate has twice been sued by the federal government for refusing to rent to minorities.

In recent years, fellow NBA legend and former Clippers GM Elgin Baylor also once sued him for racial discrimination.
