Ronda Rousey’s return to the UFC’s Octagon now has an official date.

Rousey will fight at UFC 207 on Dec. 30 as she challenges champion Amanda Nunes for the women’s bantamweight title.

The UFC announced the booking Wednesday for its year-end card at the T-Mobile Arena in Las Vegas.

Rousey (12-1, 6-1 UFC) last fought at UFC 193 on Nov. 14, 2015, when she was knocked out by challenger Holly Holm.

Rousey, one of the biggest stars the UFC and mixed martial arts has ever had, lost more than her title that night. She lost her aura of invincibility, one built on an undefeated record, 11 first-round finishes and a string of three straight fights all ending in less than 34 seconds.

Holm lost the title in first defense last March against Miesha Tate, who then lost her first title defense to Nunes in July. This will be the first title defense for Nunes (13-4, 6-1), the UFC’s first openly gay champion.

In the moments after the fight initially was anounced, Rousey sent two tweets. Among the hashtags was “#FeartheReturn.”

Since losing to Holm, Rousey has kept a very low profile in the public eye, a stark contrast from her reign as champion which included movie roles, magazine covers and television and promotional appearances.

In the past year, there was a notable appearance on “Ellen” where she revealed some of the emotions she felt after losing to Holm, as well as being the first MMA fighter to host “Saturday Night Live.” There also was a minor knee surgery.

Little else, though. That’s likely about to change as Rousey makes her much-awaited return to mixed martial arts competition.
