The first Ultimate Fighting Championship event held in Canada, UFC 83 was headlined by the long-awaited rematch between the current welterweight champion Matt Serra and the interim champion Georges St. Pierre. The card also featured six middleweight bouts (though only three of them were televised), and two Ultimate Fighter tournament winners making a debut at a new weight class: Mac Danzig at 155 lbs, and Michael Bisping at 185.
Mark Bocek vs Mac Danzig
Bocek surprised Danzig in the first round, getting a takedown and working from Danzig’s guard and half-guard from most of the round. Danzig reversed position towards the end, but it was not enough to win the round.
Danzig dropped Bocek with a knee to the chin early in the second. Danzig dominated the round both on the ground and standing, damaging Bocek with elbows and punches and taking his back at one point.
Bocek looked tired and had many small cuts on his face as the third round began. Danzig continued his assault and opened up a gashing cut over Bocek’s left eye. Referee Yves Lavigne stopped the action to check the cut, but allowed the bout to continue. Danzig got a takedown, mounted and took Bocek’s back, forcing a tapout with a rear naked choke.
