Rumors are swirling of a potential UFC lightweight title fight between champion Khabib Nurmagomedov and former champ Conor McGregor being discussed for the end of the year.

The rival superstars were in the same venue Sunday, though their paths apparently never crossed.

Nurmagomedov posted a photo of himself inside the stadium of the World Cup Final in Moscow.

McGregor viewed the action from a more prominent perch as the personal guest of Russian president Vladimir Putin.

“This man is one of the greatest leaders of our time and I was honored to attend such a landmark event alongside him,” McGregor wrote on social media. “Today was an honor for me, Mr. Putin. Thank you and congratulations on an amazing World Cup.”

Nurmagomedov, from the Russian republic of Dagestan, was the alleged target of McGregor’s bus attack in Brooklyn, for which criminal charges are still pending.

Their separate appearances at the world’s biggest sporting event occurred just after McGregor turned 30 on Saturday. Several family members, including longtime girlfriend Dee Devlin, appeared to indicate the couple is expecting their second child on social media messages wishing him well.

McGregor has not confirmed they are expecting a sibling for Conor McGregor Jr., who was born in May 2017.

McGregor has not competed in MMA since November 2016. His only fight since that date was a boxing match against Floyd Mayweather in August 2017. He is due in a New York courtroom on July 26, when it is possible he could enter a plea agreement.

UFC president Dana White has said he will not announce a fight until the legal situation has been resolved.
