Amanda Nunes admits complacency played a part in losing her bantamweight title last December against Julianna Peña. But the former two-division champion insists it was a one-time mistake and vows to redeem it Saturday in a rematch against Peña in the main event of UFC 277. Their showdown tops the main UFC 277 fight card (10 p.m. ET) from the American Airlines Center in Dallas. Nunes saw her six-year reign at bantamweight stunningly halted in the form of a second-round stoppage loss to Peña at UFC 269. Nunes told the media this week that she became too comfortable with her success and underestimated Peña in their first bout. However, Peña is determined to come out on top again and keep the belt.

Caesars Sportsbook lists Nunes as a -300 favorite (risk $300 to win $100), while Peña comes back at +250 in the latest UFC 277: Peña vs. Nunes 2 odds. In the co-main event, former flyweight champion Brandon Moreno (-200) faces Kai Kara-France (+175) for the interim belt.

UFC 277: Peña vs. Nunes preview 

Nunes (21-5) is one of the most dominant champions in UFC history and one of just four fighters to hold titles in two weight classes at the same time. The others are Conor McGregor, Daniel Cormier and Henry Cejudo. 

She had successfully defended the bantamweight title seven times, and there was a widespread belief that the division no longer offered any viable challengers because Nunes already had defeated all of them in dominant fashion. 

Peña (11-4) was awarded the title shot largely because she was the only ranked contender calling for a fight with Nunes and her confidence made for a marketable matchup. But the 32-year-old Chicago resident backed up her words by walking down Nunes and appeared to break the will of the reigning champion.

Although Peña’s win was officially scored as a rear-naked choke submission, Nunes went down after a series of strikes and appeared to concede the fight as soon as she hit the mat. 

Nunes, who is still the women’s featherweight champion, later chalked up the performance to an off night and the 34-year-old Brazilian asked for an immediate rematch. Peña didn’t hesitate to take the fight. You can only see who to back at UFC 277 at SportsLine.

UFC 277 predictions

We’ll share one of Gombas’ UFC 277 selections here: He is backing Nicolae Negumereanu (+125) to get his hand raised against Ihor Potieria (-145) in a matchup of light heavyweight prospects on the preliminary card.

Potieria (19-2) is a celebrated prospect who will bring a 15-fight winning streak into his UFC debut on Saturday. The 26-year-old Ukrainian has nine knockouts on his record and secured his spot on the UFC roster with a first-round stoppage of Lukasz Sudolski on “Dana White’s Contender Series” last September.

Negumereanu (12-1) is a versatile talent who has reeled off three consecutive victories following a loss in his UFC debut. The 27-year-old Romanian is coming off a decision win against fellow prospect Kennedy Zechukwu in March.

“I believe Negumereanu has an advantage in grappling, cardio and level of competition. His striking style isn’t the prettiest, but he stays in your face and has good durability. I believe the wrong fighter is favored,” Gombas told SportsLine. See who else to pick at UFC 277 here.
