UFC 100 took place on July 11, 2009, in Las Vegas, Nevada. The card featured five fights, including: Brock Lesnar vs. Frank Mir, Georges St. Pierre vs. Thiago Alves, Dan Henderson vs. Michael Bisping, Alan Belcher vs. Yoshihiro Akiyama, and John Fitch vs. Paulo Thiago.
Though the card featured several highly anticipated fights, the event was marred by two separate incidents.
First, during the third fight of the night, middleweight Dan Henderson caught his opponent Michael Bisping with a crushing right hand. The blow sent Bisping plummeting, slamming the back of his head on the mat. Henderson then followed up with an elbow to the head of the motionless Bisping that seemed uncalled for, considering Bisping appeared to be out cold.
During the main event, a heavyweight title bout between Lesnar and Mir, Lesnar used his twenty-pound weight advantage to pummel and pound Mir into a bloodied pulp. During the second round of the fight, Mir got himself trapped up against the fence and Lesnar was able to land numerous blows to the back of his head. The ref stopped the fight and Lesnar won his re-match with Mir, who had beaten him a year prior. However, after the victory, Lesnar began taunting his injured opponent as well as the audience. He began prancing around the octagon and flipping off the crowd as if he were back in the WWE.
In a welterweight championship fight, Thiago Alves was expected to put up a challenge for champion GSP. However, GSP immediately took control of the match, dominating Alves and sending him to the mat with masterful takedowns at every opportunity. GSP won the match in a five round decision in which he won every round of the fight.
The first fight of the night saw Yoshihiro Akiyama defeat opponent Alan Belcher in a middleweight contest. The bout went to a decision after three rounds. The fight was somewhat difficult to score, but Akiyama came out on top.
In the night’s final bout, Jon Fitch used his superior wrestling and grappling skills to defeat opponent Paulo Thiago. This fight was also decided in a three round decision.
While the card featured three of the UFC’s top fighters in Lesnar, GSP, and Henderson, the event is best remembered for the controversy surrounding the actions of Lesnar and Henderson. This may also have been the point in which it became very clear as to just how great a fighter GSP really was. GSP had already established himself as one of the best in the UFC by this point. However, the ease with which he disposed of Alves was a little surprising to many. Alves was considered a tough opponent and was expected to provide a challenge for GSP. Instead, GSP rose to the occasion and asserted himself as a truly great champion fighter.
