According to Wikipedia, which I used because I'd rather go there than the UFC site:

Middleweight Ronaldo Souza vs. Gegard Mousasi
Heavyweight Alistair Overeem vs. Ben Rothwell
Heavyweight Matt Mitrione vs. Derrick Lewis
Lightweight Joe Lauzon vs. Michael Chiesa
Featherweight Nik Lentz vs. Charles Oliveira
Flyweight John Moraga vs. Justin Scoggins

That's the main card.

Since I know you aren't a huge fan... you're pretty much guaranteed a fun fight when Joe Lauzon is fighting. He is tied with Anderson Silva for the most bonuses (for like, fight of the night, submission of the night, etc) at 12. Dude comes to scrap, win or lose. Love that guy.

Someone is going to sleep in the Overeem/Rothwell fight. Overeem hits really really hard (when he isn't tired) and Rothwell also hits hard but can also take a shot.

Charles Oliveira and Nik Lentz could be a good fight. I hope it goes to the ground though because Oliveira is a lot more fun on the ground than standing.

John Moraga is an exciting flyweight. I don't know a thing about Scoggins. Name sounds familiar.

But Souza and Mousasi is what I'm looking forward to. Mousasi is one of my favourite fighters. He's excellent all-around, with elite striking and a great ground game... only weakness really has been wrestling, but he was fighting a weight class above for years and he was smaller than most people in that division. Now he's back to Middleweight, his natural weight class.

Souza has an elite ground game, great wrestling and his striking is getting a lot better. They've actually already fought years ago and Mousasi did an upkick while he was on the ground and knocked him out, lol. I don't think that will happen again but I'm still pulling for Mous.

It's actually not a bad card at all. Much better than the PPV this coming weekend.
