According to Dave Meltzer, following his unanimous decision loss to Frankie Edgar (30-27 on all cards) at UFC 98, Sean Sherk, shirtless and still wearing his gloves, ran out of the MGM Grand and down Harmon Ave.. He was seen near the Hard Rock. He returned to the venue approx. fifteen minutes later. There was some hubbub because Sherk left without providing a post-fight urine sample to the NSAC, but Sherk wasn't on the 'randomly' generated list of fighters who were supposed to provide following their fights. So it seems he didn't take the loss well.
