Roger Goodell has been sent letters signed by 50 U.S. senators urging the NFL to change the name of the Washington Redskins.

The senators draw a parallel between the NBA's no-tolerance policy regarding the racist comments made by Los Angeles Clippers owner Donald Sterling and asks the NFL to act similarly.

"Today, we urge you and the National Football League to send the same clear message as the NBA did: that racism and bigotry have no place in professional sports," the senators write. "It's time for the NFL to endorse a name change for the Washington, D.C. football team.

"The despicable comments made by Mr. Sterling have opened up a national conversation about race relations. We believe this conversation is an opportunity for the NFL to take action to remove the racial slur from the name of one of its marquee franchises."

Daniel Snyder has defiantly opposed a name change.

The NFL has stood behind Snyder and issued its own response Thursday to the news of the senators' letter.

"We have not received the letter, but the NFL has long demonstrated a commitment to progressive leadership on issues of diversity and inclusion, both on and off the field," NFL spokesman Brian McCarthy said in a statement. "The intent of the team's name has always been to present a strong, positive and respectful image. The team name is not used by the team or the NFL in any other context, though we respect those that view it differently."
