ESPN suspends Rob Parker for comments he made questioning 'blackness' of Redskins QB RG3

NEW YORK, N.Y. - ESPN has handed commentator Rob Parker a 30-day suspension for questioning the "blackness" of Redskins quarterback Robert Griffin III.

The network announced the suspension Thursday, a day after Parker apologized for comments he made during a Dec. 13 episode of "First Take".

Posting to Twitter, Parker said, "I blew it and I'm sincerely sorry. I completely understand how the issue of race in sports is a sensitive one and needs to be handled with great care."

Parker, who is black, was discussing Griffin's role as an African-American quarterback when he noted that Griffin has a white fiance and is rumoured to be a Republican.

Among his comments, Parker said, "Is he a brother or a cornball brother?"
