UFC 148 emanates from Las Vegas this Saturday night with the biggest rematch in MMA history.
UFC 117 was the much-publicized first battle that nearly saw the end of Anderson Silva‘s long reign atop the UFC’s middleweight division.
Chael Sonnen dominated with wrestling and ground and pound until he was caught in a triangle choke late in the fifth and final round.
When the two meet with bad intentions on Saturday, Silva will need to use what he learned from the first fight to ensure another title defense.
Here are five key takeaways from their first fight at UFC 117.
