UFC 66

UFC 66: Liddell vs. Ortiz 2 was a mixed martial arts event held by the Ultimate Fighting Championship (UFC) on December 30, 2006, at the MGM Grand Garden Arena in Las Vegas, Nevada.

The main event featured a highly anticipated light heavyweight championship rematch between then-champion Chuck Liddell and Tito Ortiz. Their first fight, UFC 47 in 2004, saw Liddell win by knockout. The co-main event featured a welterweight bout between Karo Parisyan and Josh Burkman.

The card also included notable fighters such as Forrest Griffin, Stephan Bonnar, Keith Jardine, and Gabriel Gonzaga. The event was a significant commercial success, achieving a large pay-per-view buyrate, attributed to the drawing power of Liddell and Ortiz and the overall growth of the UFC at the time. The event is remembered for its action and the culmination of the Liddell-Ortiz rivalry, at least at that point in their careers. Liddell defeated Ortiz by TKO in the third round, retaining the UFC Light Heavyweight Championship.
