She’s back! Former UFC Women’s Bantamweight Champion “Rowdy” Ronda Rousey returns from an extended year-long layoff to challenge current champ Amanda “Lionheart” Nunes for the 135-pound gold. The matchup will take place in the main event of the evening for UFC 207 in Las Vegas on Friday, December 30th, 2016. The UFC 207 fight card is stacked with 12 scheduled bouts, with preliminary action getting underway at 6:30 p.m. (ET) on UFC Fight Pass and continuing on FOX Sports 1 at 8 p.m. The main card will be live on Pay-Per-View at 10 p.m., and all betting lines will be made available at 5Dimes Sportsbook. Kicking things off for the UFC 207 televised prelims on FOX Sports 1 will be a middleweight contest between Antonio Carlos Junior and Marvin Vetorri. “ACJ” suffered a big upset third round TKO loss against Daniel Kelly to start off the year, but since returned to the win column with a third round rear naked choke win over Leonardo Leleco. He plans to make it two straight on December 30th when he squares off against the 23-year-old. Vettori scored a first round guillotine choke submission win over Alberto Uda four months ago, which made for an impressive Octagon debut for the Italian. He enjoys a six fight winning streak heading into this 185-pound contest and looks to make it seven by taking out the TUF: Brazil winner. Welterweights take center stage for the evening’s next bout, as veteran Mike Pyle takes on TriStar Gym product Alex Gacia in a pairing of two finishers who are coming off knockout defeas themselves. Both 170-pounders will be in dire need of victory heading into this one, and it is likely that one of them will be adding another highlight to their reels with an incredible finish before the Las Vegas crowd. Staying in the 170-pound division for the next contest, veteran Dong Hyun Kim returns from an extended year-long layoff in an effort to make it three wins in a row for himself inside the Octagon when he takes on former Strikeforce welterweight champion Tarec Saddiefine. Saffiedine is coming off a unanimous decision loss to Rick Story and is looking to get back into the win column with an impressive victory over Kim in this rare “winner vs loser” match-up in the UFC’s welterweight division. Welerweight action continues to wrap up the FOX Sports 1 televised prelims of the evening, as former UFC welterweight champion Johny Hendricks will aim to snap a two-fight losing skid by taking out Elevation Fight Team’s Magny. This is a “do or die” match-up for only Hendricks, as he has said that he will retire from the sport of mixed martial arts, should he fail to get his hand raised for the third consecutive bout. TUF 16 veteran Magny recently saw his impressive three fight winning streak snapped by Lorenz Larkin via first round TKO and he plans to get back into the win column in impressive fashion and make another run for what Hendricks used to hold, the welterweight title. It all starts with a victory over the former champ himself, so he will be looking to leave it all inside the Octagon when they square off on December 30th.
