Saturday evening marks the UFC's debut on FOX in what is a very important night for the sport of mixed martial arts.
Over the past several years, the sport of MMA has been growing rapidly and Saturday the sport's most prominent promotion, the UFC, has a chance to bring the sport to new heights with a great showing on FOX.
In order to ensure that those who do tune in do not regret that decision, the UFC had to be careful in selecting a fight to headline the evening's event.
Most would agree that they chose wisely in selecting UFC heavyweight champion Cain Velasquez vs. Junior dos Santos to be the main event.
The UFC's heavyweight division has been long-criticized for its lack of depth and legitimate contenders, but two legitimately elite heavyweights will step into the cage and duke it out on UFC's network debut.
This may be the most important heavyweight fight in the history of the sport.
Junior dos Santos is one of the most feared strikers in MMA today and is undefeated since entering the UFC, defeating the likes of Gabriel Gonzaga, Mirko Cro Cop, Roy Nelson and Shane Carwin.
So, what does a win for dos Santos mean for the heavyweight division?
A win for dos Santos means that the UFC's heavyweight division might have its first ever dominant champion.
Most weight classes have had dominant champions who were able to hold on to their belts for many title defenses.
Names like Anderson Silva, Georges St-Pierre, Matt Hughes and Tito Ortiz come to mind.
The UFCs heavyweight division has had no such champion; indeed, no champion has been able to defend their title more than two times.
Cain Velasquez has looked head and shoulders better than every fighter he has faced in the UFC and if Junior beats him tonight, it's safe to assume that there isn't much of anyone out there who will be able to challenge him.
If Junior dos Santos wins in their battle in Anaheim, CA, it means the UFC's heavyweight division might finally get its Anderson Silva.
