Bruce Levenson will sell the Atlanta Hawks after it was discovered he wrote racist comments about African-American fans in an email.

NBA commissioner Adam Silver and Levenson made the announcement Sunday morning with joint statements. Silver discussed the issue with some owners late last week, but many other owners and team officials did not know of it until Sunday's announcement, league sources told Yahoo Sports.

Levenson apologized for the August 2012 email, which was sent to Hawks general manager Danny Ferry and stereotyped the differences between black and white fans in Atlanta.

“Over the past several years, I’ve spent a lot of time grappling with low attendance at our games and the need for the Hawks to attract more season ticket holders and corporate sponsors," Levenson said in the statement. "Over that time, I’ve talked with team executives about the need for the Hawks to build a more diverse fan base that includes more suburban whites, and I shared my thoughts on why our efforts to bridge Atlanta’s racial sports divide seemed to be failing.

"In trying to address those issues, I wrote an email two years ago that was inappropriate and offensive. I trivialized our fans by making clichéd assumptions about their interests (i.e. hip hop vs. country, white vs. black cheerleaders, etc.) and by stereotyping their perceptions of one another (i.e. that white fans might be afraid of our black fans). By focusing on race, I also sent the unintentional and hurtful message that our white fans are more valuable than our black fans.

"If you're angry about what I wrote, you should be. I'm angry at myself, too. It was inflammatory nonsense. We all may have subtle biases and preconceptions when it comes to race, but my role as a leader is to challenge them, not to validate or accommodate those who might hold them."
