Ultimate Fighting Championship (UFC) will present UFC 148: "Silva vs. Sonnen 2" from the MGM Grand Garden Arena in Las Vegas, Nevada, TONIGHT (Sat., July 7, 2012) in a rematch nearly two years in the making.

That's right, Anderson Silva already defended his 185-pound title against Chael Sonnen once before, at UFC 117 back in August 2010, but the challenger came so close to winning (and the division ran out of viable contenders) that Sonnen gets another crack at the crown later on this evening in "Sin City."

If you missed any or all of their first encounter, no worries, the promotion has released the full fight video to help get you up to speed and whet your combat cravings until they step inside the cage here in just a few hours. At the time, "The Spider" was seemingly invincible, until the most unlikely 23 minutes in the history of middleweight title defenses unfolded.

Sonnen would dominate the entire fight but eventually succumb to a fifth round triangle choke. He left the Octagon having out-struck the champion 320-64. But was it a rib injury? Or does Sonnen really have the Brazilian's number?

We'll find out tonight on pay-per-view.
