At the Mandalay Events Center in Nevada this summer comes one of the biggest events in UFC history: UFC 100. There will be two championships on the line this year when these fantastic fighters take each other on. The Welterweight Title will be fought between Georges St-Pierre and Thiago Alves. St-Pierre is highly talented as the wrestling side of the fight, while Alves is a Muay Thai master that can strike almost anyone down. It will be an amazing battle. But the main event will be the Heavyweight Title bout between champion Brock Lesnar and Frank Mir, the interim champion. This is a battle that will show who is really the champion of the unified title. They had to cancel their previously scheduled fight when Mir was injured during training and had to call it off. This will be amazing to see these two finally face off for the first time in many years. If you are a fan of these battles, make sure to get your UFC tickets today and enjoy an epic battle!
