ESPN spokesman Josh Krulewitz said: "Following yesterday's comments, Rob Parker has been suspended until further notice. We are conducting a full review."
Parker, appearing on ESPN's "First Take" on Thursday, was asked about Griffin's role as a black quarterback. Parker questioned Griffin's "blackness."
"Is he a brother or a cornball brother?" said Parker, who is black.
Later, he said he wanted to find out more about Griffin and how he deals with black teammates and others in Washington.
"We all know he has a white fiancée,"
he said. "There was all this talk about he's a Republican, which, there's no information [about that] at all. I'm just trying to dig deeper as to why he has an issue. Because we did find out with Tiger Woods, Tiger Woods was like, I've got black skin, but don't call me black. So people got to wondering about Tiger Woods early on."
Robert Griffin II, the quarterback's father, told USA Today Sports Thursday night : "I wouldn't say it's racism. I would just say some people put things out there about people so they can stir things up."
DeMaurice Smith, executive director of the NFL Players Association, told The Washington Post in an email Friday: "Robert can certainly take care of himself. Nonetheless, I hope that our men and for that matter, my own kids, will never beg for authenticity from someone who can only talk about the things that other people have the courage to do. People need to be held accountable for the offensive things that they say."
