It's a big night for UFC fans. UFC legends Vito ‘The Phenom’ Belfort and Dan ‘Hendo’ Henderson go toe-to-toe at UFC Fight Night 32. These two are serious fighters with long and distinguished careers. And while they usually fight in the middleweight division, they’ll be competing at the light heavyweight level tonight. Confused about what we're talking about? Allow us to break it down.

1. UFC (Ultimate Fighting Championship) is a mixed martial arts competition. So basically, it's completely badass, and even if you're not into it, you can't help but getting excited while watching. 

2. It could be argued that these two men fighting for their careers, with Hendo in particular, looking for a win as this is the last fight on his current UFC deal.

3. They have a history. These two veterans first met back in 2006 when Hendo defeated Belfort in a unanimous decision, so there’s seven long years of resentment bubbling under the Brazilian’s battered visage.

Essentially, this is going to be the sporting equivalent of two grizzled old lions duking it out on the Serengeti. And don’t let anyone tell you that’s not entertainment. Check it out on FOX Sports at 8 p.m. EST. Yessss.
