UFC 98: Evans vs. Machida was a mixed martial arts event held by the Ultimate Fighting Championship (UFC) on May 23, 2009 in Las Vegas, Nevada.
Quinton Jackson, former UFC Light Heavyweight champion, was to fight the undefeated current champion Rashad Evans but had to undergo arthroscopic surgery to repair ligament damage in his jaw that he received in a previous training camp. Instead, Evans headlined the card against fellow undefeated contender Lyoto Machida.
During a flurry of punches from Machida, Evans started trash talking Machida telling him 'his hands were made of pillows'. Machida continued his onslaught, knocking the champion out. Evan's timely photograph of his face during the knockout became an infamous meme called "Shad face" amongst MMA fans.
