Boxer Evander Holyfield required 15 stitches in his right ear after being bitten twice Saturday night during a professional bout with heavyweight boxer Mike Tyson Saturday in Las Vegas. The bite has Julio Garcia, the doctor who repaired Holyfield's severed ear, worried about possible infection. The Centers for Disease Control and Prevention says that the chances of contracting HIV from a human bite is virtually infinitesimal, but doctors recommend an HIV test nonetheless. Because Nevada's boxing commission requires pre-bout mandatory HIV testing, both fighters were tested before the fight. There is no indication that Tyson tested positive for HIV or any other bloodborne illness.
