In the UFC 107 co-headliner, heavyweight Frank Mir rebounded from a July loss to Brock Lesnar and got back into title contention by making quick work of Cheick Kongo, knocking him down in the opening minute then putting him to sleep with a guillotine choke just 72-seconds into the matchup.

Welterweight contender Jon Fitch remained in the mix at 170-pounds but went the distance for his sixth-straight fight, topping Mike Pierce with 29-28 scores across the board for his third-straight victory.

Kenny Florian forced Clay Guida to submit to a rear naked choke in the second round at UFC 107, bouncing back from an August loss to Penn to join a handful of contenders in the muddled lightweight division, while heavyweight Stefan Struve picked up his third-straight win by topping Paul Buentello by majority decision to kick of the event’s main card.

UFC President Dana White announced the bonuses at the UFC 104 post-fight press conference.

Struve earned “Submission of the Night” honors for his slick triangle choke of newcomer Chase Gormley in the first bout of the night, nabbing the choke from the top before rolling to his back to finish the submission with 56-seconds remaining in the opening round.

“Knockout of the Night” would have been awarded to Anthony Johnson for his 41-second thrashing of Yoshiyuki Yoshida, but Johnson’s failure to make weight ruled him ineligible and allowed Barry to win the award. After an exciting first frame, Barry settled in and blasted Hardonk with combinations, eventually dropping him to the canvas where he was quickly finished with a pair of heavy hands.

Barry and Hardonk were awarded “Fight of the Night” for their Spike TV-televised scrap.

In a decision that was met with boos from the live crowd and claims of robbery and calls for an immediate rematch from online fans, the judges awarded Machida the victory with 48-47 scores despite Rua winning the bout on nearly every observer’s scorecard.

Rua’s strategy relied on damaging leg and body kicks that left Machida battered after the five-round technical showdown, while Machida connected less frequently with precision strikes. Despite more frequent and damaging blows, the decision was given to the reigning champ, who was defending the title for the first time since winning the belt from Rashad Evans in May.

Machida remains undefeated, improving to 16-0 in the victory with his eight-straight wins inside the Octagon tied for second-best in the promotion’s history, while Rua falls to 18-4 in defeat.

In the UFC 104 co-headliner, Cain Velasquez cemented his status as a top heavyweight contender with a dominating win over Ben Rothwell. After blitzing the IFL veteran for the entirety of the opening round, Velasquez picked up where he left off in the second, taking Rothwell to the ground and quickly finishing him with punches.

Velasquez, now 8-0 on his career with five-straight UFC wins, remains in line for a future title show, while Rothwell falls to 30-7 and will return to the Octagon in search of his first UFC win to get him back on track.

In other main card action, Gleison Tibau used dominant takedowns to pick up a decision over Josh Neer, Joe Stevenson forced Spencer Fisher to tap to a barrage of elbows, and Antony Johnson earned a 41-second knockout of Yoshiyuki Yoshida.

On the preliminary card, The Ultimate Fighter 8 winner Ryan Bader earned a unanimous decision over Eric Schafer, Pat Barry kicked off the Spike TV card with an impressive second-round TKO of Antoni Hardonk, Chael Sonnen dominated Yushin Okami en route to a unanimous decision win, and Jorge Rivera, Kyle Kingsbury, and Stefan Struve also earned wins.

The official results for UFC 104 were:

• Lyoto Machida (c) def. Mauricio “Shogun” Rua via unanimous decision (48-47, 48-47, 48-47)
  UFC Light Heavyweight Championship
• Cain Velasquez def. Ben Rothwell via TKO (strikes) — Round 2, 0:58

Light heavyweight champ Lyoto Machida (202.5) and challenger Mauricio “Shogun” Rua (204.5) successfully made weight for the UFC 104 main event, as did co-headliners Cain Velasquez (238) and Ben Rothwell (265).

Welterweight knockout artist Anthony Johnson will likely be moving to middleweight for his next bout after weighing in 6 pounds over the division’s 170 pound limit. Johnson will forfeit 20 percent of his purse to opponent Yoshiyuki Yoshida, who weighed in at 170 pounds, but the fight will go on as scheduled.

Lightweights Josh Neer and Gleison Tibau both narrowly missed the division’s 155 pound limit for their matchup, but have agreed that neither will need to shed extra weight, instead meeting at a 157 pound catchweight.
