Conor McGregor will get the chance to make history this March, challenging Rafael dos Anjos for the UFC lightweight title at UFC 197.

Officials confirmed the main event, along with a co-main event featuring Holly Holm defending her bantamweight belt vs. Miesha Tate on Tuesday.

Set for March 5 from the MGM Grand Garden Arena in Las Vegas, McGregor will look to add 155-pound gold to the featherweight strap he currently holds. He won the 145-pound title with a 13-second knockout of Jose Aldo last month.

Previously, B.J. Penn and Randy Couture have claimed UFC titles in multiple weight classes, but no one has ever held titles in two divisions at the same time. Penn challenged for the UFC welterweight title while he was the lightweight champion.

Dos Anjos made his first title defense in December with a first round finish of Donald Cerrone. He won the belt with a victory over Anthony Pettis.

Holm, meanwhile, won the title with a dominating performance over Ronda Rousey this past November. Tate, a former title contender, previously held the Strikeforce belt.

A rematch between Holm and Rousey was expected, but with “Rowdy” taking time off to film movies, Tate was awarded the title opportunity.

Tickets go on sale to the general public January 22, with earlier pre-sale events likely that week.
