On Saturday, Dec. 28, the UFC hosted UFC 168: Weidman vs. Silva II from the MGM Grand Garden Arena in Las Vegas.

The night’s main event featured one of the biggest rematches in the sport’s history, as middleweight champion Chris Weidman looked to prove that his knockout of Anderson Silva at UFC 162 in July was no fluke. The undefeated Weidman stunned the Brazilian and the MMA world with the second-round finish of “The Spider.”

In the co-main event, women’s bantamweight champion Ronda Rousey faced a familiar foe in her fellow Ultimate Fighter 18 coach, Miesha Tate. The pair previously clashed under the Strikeforce banner, with Rousey forcing Tate to submit to her trademark armbar.

Rounding out the main card, heavyweights Josh Barnett and Travis Browne battled for position in the title picture, hard-nosed lightweight Jim Miller took on Brazilian Fabricio Camoes, and TUF winner Diego Brandao clashed with Dustin Poirier in a featherweight affair.

The 11-fight event kicked off at 7 p.m. ET with two fights streaming live on the promotion’s Facebook and YouTube pages. Four additional bouts followed on Fox Sports 1 at 8 p.m. ET, with the pay-per-view main card beginning at 10 p.m. ET.

Weidman retains middleweight title after Silva breaks leg

Middleweight champion Chris Weidman retained his title, defeating Anderson Silva by second-round TKO after Silva broke his leg.

Weidman shot for a single-leg takedown quickly, but he could not hold Silva on the mat. Silva threw knees from the clinch, but a right hand from Weidman hurt the Brazilian. Weidman followed Silva to the mat, but Silva recovered and held his guard. Weidman dropped elbows from the top position, but Silva survived the round.

In the second round, the pair exchanged on the feet. Weidman landed a big kick to the body of Silva. Silva looked to answer with a kick of his own, but Weidman checked it and Silva’s lower leg shattered. The Brazilian fell to the mat in agony and Weidman retained his belt.

Rousey armbars Tate to retain women’s bantamweight title

UFC women’s bantamweight champion Ronda Rousey retained her title with a third-round armbar over bitter rival and fellow Ultimate Fighter coach Miesha Tate.

The ladies came out swinging and Rousey quickly moved in for a takedown. Tate worked her way back to her feet, but it was short-lived. Rousey worked from the top, but Tate reversed into her guard. Rousey attacked with a triangle attempt from her back, but Tate was able to escape.

In round two, Rousey dominated. She turned multiple takedown attempts into big throws and planted Tate on her back. From the top position, Rousey battered Tate with punches. Midway through the round, Rousey attacked Tate’s left arm, but used it to move to the mount. After softening Tate up with punches, she went for her trademark armbar, but Tate managed to escape as the round closed.

Rousey wasted little time in round three, again attacking Tate’s left arm. Rousey locked on the fight-finishing armbar less than a minute into the round to retain her title.

Browne crushes Barnett

Heavyweight Travis Browne continued his march toward the title with a first-round knockout of former champion Josh Barnett.

Barnett quickly looked to close the distance as the fight began. Browne shrugged him off briefly and landed a big knee. Barnett again worked hard for a takedown, but Browne unleashed a barrage of elbows that put Barnett out cold just one minute into the fight.

Miller submits Camoes

Lightweight Jim Miller got back in the win column, submitting Brazilian Fabricio Camoes via armbar in the first round.

The pair exchanged combinations early. Camoes missed with a head kick, but scored with a big left hand to slow Miller’s advance. Another head kick from the Brazilian connected, but Miller turned it into a takedown. It was short-lived as Camoes reversed into the top position. However, Miller showcased how dangerous his guard really is, forcing the BJJ black belt to succumb to an armbar.

Poirier stops Brandao

Featherweight Dustin Poirier made Brazilian Diego Brandao pay for missing weight, scoring a violent, first-round TKO.

The two kept their distance early and Poirier used his reach advantage to get the better of the exchanges. Brandao connected with an overhand right that put Poirier on his butt, but Poirier quickly recovered. Brandao looked for a takedown, but he could not keep Poirier on the mat. Along the fence, Poirier unloaded with a barrage of strikes that hurt Brandao badly. Poirier smelled blood and flurried, forcing the referee to halt the bout just seconds before the opening round came to a close.

Preliminary Card Summary

There was a changing of the guard in the middleweight division as TUF 17’s Uriah Hall stopped TUF 1 alum Chris Leben by TKO. Hall opened with a flying knee that dropped Leben. Leben recovered, but found himself absorbing counter shot after counter shot. Late in the opening round, Hall delivered a big right hand that sent Leben to the mat once again. Hall flurried, but the bell to end the round sounded. However, the doctor stepped in stop the contest between rounds.

Lightweight Michael Johnson scored a big, second-round knockout of Brazilian Gleison Tibau. The pair spent the first round exchanging combinations and setting a high pace. That pace took its toll on Tibau in round two, as he was a step slower than Johnson. Johnson delivered a big left hand that buckled Tibau and sent him crashing to the canvas unconscious.

In an entertaining, back-and-forth featherweight tilt, Dennis Siver edged out Manny Gamburyan by unanimous decision. Siver scored in the opening round with heavy shots and a takedown. Gamburyan turned the tide in round two, putting Siver on his back and opening up a cut on his forehead with an elbow. Siver rebounded in the final frame, controlling Gamburyan throughout and earning the win on the scorecards.

Welterweight John Howard earned his second straight Octagon win, taking home a unanimous decision over Siyar Bahadurzada. The pair spent a large portion of the opening round feeling one another out, but Howard scored with a takedown and began to impose his will on the Afghan fighter. Both fighters swung for the fences in round two, but Howard slammed Bahadurzada to the mat. Round three was all Howard as he mounted Bahadurzada and rained shots until the final bell.

TUF: Brazil alum William Macario battered veteran Bobby Voelker on his way to a lopsided unanimous decision win. The Brazilian peppered Voelker with right hands and knees early in the contest, mixing in a takedown from time to time. Macario opened a big cut on Voelker’s head with an elbow and then another on Voelker’s nose that prompted the doctor to check the cut near the end of the second round. Despite the blood, Voelker continued to fight. However, his efforts were in vain as Macario walked away with the win.

Featherweights Robbie Peralta and Estevan Payan kicked off the night with a back-and-forth battle that saw Peralta score a third-round knockout. Payan was taken down multiple times early in the fight, but reversed the positions and held Peralta down from side control. Knowing he was down on the scorecards, Peralta went for broke in round three, overwhelming Payan just seconds into the stanza.
