NEW YORK | Don Imus has once again injected race into his radio show.

During an on-air conversation Monday about the arrests of suspended Dallas Cowboys cornerback Adam "Pacman" Jones, Imus asked, "What color is he?"

Told by sports announcer Warner Wolf that Jones is "African-American," Imus responded: "There you go. Now we know."

Civil rights leader Al Sharpton issued a statement calling the exchange disturbing "because it plays into stereotypes." He says his National Action Network was still deciding how to respond.

Imus was fired from his previous show last year after he made a racially charged comment about the Rutgers women's basketball team, which included former E.C. Central star Dee Dee Jernigan

Representatives for Imus and WABC Radio haven't returned calls.
