Most of UFC's fights are naturally on Pay-Per-View, but tonight, they're giving us a treat. In a move to crush the Affliction MMA league, which is having a Pay-Per-View event tonight, UFC decided to make tonight's fights free to watch on SpikeTV starting at 9pm EST. And, even more impressive, UFC has one of their biggest stars, Anderson Silva, fighting tonight to draw as many viewers as possible.

Silva is the reigning middleweight UFC champion, and is considered by many people to be the best fighter in the world, period. Meaning in MMA, boxing or whatever.

It's hard to disagree. Silva is the closest thing to perfection that MMA boasts right now with a record of 22 wins and 4 losses. Silva's greatest strength as a fighter is the seamless way he blends all the MMA styles – boxing, Thai boxing, Brazilian Jiu-Jitsu – all into one, more so than any other fighter in the UFC, which is why his style is talked of as that of a complete martial artist.

What will be interesting to see tonight is he can handle the additional 20 pounds he packed on for this fight. Silva is attempting to climb the UFC light heavyweight mountain, and he has said he wants to be both the light heavyweight champion and the middleweight champion at the same time.

Silva's opponent, James Irvin, is a light heavyweight. But since the fight was put together with only six weeks notice, and Silva had little time to train at his higher weight, this fight is almost the equivalent of a middleweight versus a light heavyweight.

Irvin is obviously no slouch. He possesses a massive right handed punch and his record stands at 14 wins, 4 losses, and 1 tie. This will certainly be a fight of skill versus power.
