After a promising start to his UFC career that saw O’Brien win his first three fight inside the Octagon, including a victory over Heath Herrting, to push his undefeated record to 10-0, “Irish” suffered back-to-back losses Andrei Arlovski and Cain Velasquez. After picking up a split decision win over Christian Wellisch in January in his light heavyweight (205-pound) debut, the former heavyweight O’Brien was submitted by Jon Jones in his most-recent bout in July at UFC 100.

Mir, who suffered a second-round knockout to Brock Lesnar in the UFC 100 main event, must sit out until September 10 following the loss. St-Pierre defeated Alves by unanimous decision in the UFC 100 co-headliner but tore his groin in the process and must sit out until January 8 unless the injury is cleared by a doctor, while Alves remains suspended until August 11 for precautionary reasons. Bisping was suspended until September 10 after suffering a brutal second-round KO at the hands of Dan Henderson at the 11-bout pay-per-view event, which took place at the Mandalay Bay Events Center in Las Vegas.

Another bout has been added to the unofficial lineup for UFC 100 as rising light heavyweight Jon Jones will take on Jake O’Brien on July 11th in Las Vegas, according to The Garv.

In his debut in the new class “Irish” defeated Christian Wellisch via split decision on the UFC 94 preliminary card in January.

Georges St-Pierre Punches BJ Penn at UFC 94

On a card dominated by uneventful decisions, UFC 94’s top two bouts delivered as Georges St-Pierre dominated BJ Penn on the ground en route to a fourth-round TKO victory while top light heavyweight contender Lyoto Machida used his awkward style to remain undefeated by scoring a first-round knockout of the previously unbeaten Thiago Silva.

A sell out crowd of 14,885 at the MGM Grand Garden Arena, which generated a live gate of $4.3 million, erupted as St-Pierre and Penn made their entrances to the octagon for their historic main event matchup that is expected to shatter the current pay-per-view buy record held by UFC 66.

The first round saw both fighters exchange on the feet as GSP unsuccessfully worked to take Penn to the ground. Early in the second, however, St-Pierre succeeded in not only getting Penn to the canvas, but passing into side control and pounding away on Penn. After again dominating Penn on the ground in the third-round, St-Pierre poured it on in the fourth, pounding away with elbows and hammer fists that had Penn struggling to survive. Despite escaping the round, Penn’s corner had seen enough and, along with the advice of the doctor, referee Herb Dean called a stop to the contest, awarding the TKO victory to St-Pierre, who retained the UFC welterweight championship with the main event victory.

St-Pierre, who improved to 18-2 with the win, will next fight Thiago Alves, while Penn, who dropped to 13-5-1 with the loss, is likely to fight Kenny Florian next.

In the evening’s co-headliner, Lyoto Machida’s unorthodox style again proved difficult to counter as he dropped Thiago Silva twice early in the first round before putting him on the canvas with a trip takedown late in the frame. Machida pounced with only seconds remaining in the first, connecting with a perfectly-placed punch to the head that knocked Silva unconscious. A second punch sealed the knockout win as Machida delivered the impressive stoppage victory he needed to secure a likely title shot against current 205-pound title-holder Rashad Evans this summer.

Machida’s record now stands at 14-0, including six-straight wins in the UFC, while Silva’s first loss gives him a 13-1 career mark.

The two stoppage victories salvaged what was an otherwise forgettable night as the remaining eight fights all went to decision. On the main card, Jon Jones showed potential with a unanimous decision victory over Stephan Bonnar, Karo Parisyan topped Dong Hyun Kim via split decision, and Clay Guida handed Nate Diaz his first loss in the UFC with split scorecards in an entertaining opener.

Jon Fitch, Thiago Tavares, John Howard, Jake O’Brien, and Dan Cramer picked up decision victories on the UFC 94 preliminary card.

After the event, the UFC announced that Howard’s victory over Chris Wilson and Guida’s win against Diaz were the “Fights of the Night” and each of the four participants earned $65,000 “fight night” bonuses. Though deserving, the evening’s $65,000 “Knockout of the Night” award went to Machida by default, who scored the only knockout on the card with his late first-round stoppage of Silva. Because UFC 94 featured no submission stoppages, a “Submission of the Night” bonus was not awarded.

According to MMAJunkie.com the matchup is close to being finalized.

O’Brien emerged as a heavyweight up-and-comer with three-straight victories to start his UFC career, including a victory over veteran Heath Herring, but next suffered back-to-back losses to Andrei Arlovski and Cain Velasquez, the first two defeats of his young career.

After suffering a first-round knockout to Cheick Kongo in his UFC debut Wellisch rebounded to score back-to-back UFC wins over Anthony Perosh and Scott Junk. However, he was stopped by surging heavyweight Shane Carwin in just 44-seconds at UFC 84 in May.

The UFC welterweight title will be on the line in the UFC 94 main event, as UFC 170-pound champion Georges St-Pierre rematches 155-pound title-holder BJ Penn.
