Conor McGregor to fight Eddie Alvarez at UFC 205 in NYC Nov. 12

Conor McGregor returns to the octagon at UFC 205 as the event headliner against Eddie Alvarez.

McGregor, the UFC featherweight champion, faces lightweight champion Alvarez at Madison Square Garden on Nov. 12 with the opportunity to become the first fighter to hold belts in multiple weight classes in a champion vs. champion superfight.

It's the first ever UFC event in New York, which lifted a ban on mixed martial arts after the sport worked almost 10 years to legalize it.

McGregor (20-3) won his last fight, a rematch with Nate Diaz at UFC 202, which was contested at welterweight.

Alvarez (28-4) defeated Gilbert Melendez and former UFC and WEC champ Anthony Pettis before knocking out Rafeal dos Anjos in the opening round of their July 7 fight in Las Vegas to claim the lightweight belt.

The bout with McGregor allowed Alvarez to leapfrog Khabib Nurmagomedov (23-0), who had a signed bout agreement for UFC 205.
