Sanchez and Guida arrived in Sin City with reputations for nonstop cardio, and they didn’t disappoint. The first round is one of the most memorable in MMA history, as Sanchez blasted Guida with punches against the fence and landed a head kick that looked like a surefire KO. Somehow, Guida survived and fought back, with the pace hardly slowing from the opening seconds to the final bell.
It was Sanchez who earned a split decision and a title shot at lightweight champion B.J. Penn later that year.
A fan favorite fight for years, this bout officially got its due from the UFC when it was inducted into the promotion’s Hall of Fame last July.
