For four and a half rounds Chael Sonnen dominated UFC middleweight champion Anderson Silva. In the final minutes of the fifth round, Silva turned the tables with an amazing come from behind triangle choke. Sonnen started strong, landing a left hand that rocked Silva and never let up for the entire fight. But Silva never lost faith, continuing to fight off his back and eventually securing the submission lock to finish the fight.

Sonnen did a masterful job building hype for a fight that might have otherwise seemed like a routine defense for Silva. His trash talk varied, sometimes hilarious, other times of questionable taste (like telling the world Lance Armstrong gave himself cancer by using performance enhancing drugs). But by the night of the fight, the MMA world was abuzz.

Silva stayed above the fray, vowing to do his talking in the cage. He won his twelfth consecutive fight in the Octagon and defended his middleweight title for the seventh time, both UFC records. After the fight Silva claimed a serious rib injury had slowed him down, but it wasn't enough to prevent one of the most amazing comebacks in UFC history.
