The National Football League is used to big, bruising battles. But on Friday, it announced that it was probably staying out of one of the roughest fights in Washington: the war over Obamacare.

Earlier this week, Health and Human Services Secretary Kathleen Sebelius disclosed that the administration was in talks with the NFL and other sports leagues to help promote the law, which enters a new phase as advocates prepare to begin enrolling millions in health insurance this fall.

On Friday, Sens. Mitch McConnell of Kentucky and John Cornyn of Texas issued a stern warning to sports organizations not to partner with the administration on an issue marked by such "divisiveness and persistent unpopularity."

Asked about the letter, NFL spokesman Greg Aiello said the league had not made any commitment.

"We have responded to the letters we received from members of Congress to inform them we currently have no plans to engage in this area," he said in an e-mail.
