Evander Holyfield vs. Mike Tyson II, billed as The Sound and the Fury and afterwards infamously referred to as The Bite Fight, was a professional boxing match contested between Evander Holyfield and Mike Tyson on June 28, 1997, for the WBA Heavyweight Championship. It achieved notoriety as one of the most bizarre fights in boxing history after Tyson bit off a part of Holyfield's ear. Tyson was disqualified from the match and lost his boxing license, though it was later reinstated.

The match began with Holyfield dominating Tyson. Holyfield won the first three rounds. At 2:19 of the first round, an overhand right punch from Holyfield stunned Tyson, but Tyson fought back, immediately pushing Holyfield backwards. At 32 seconds into the second round, Holyfield ducked under a right punch from Tyson. In doing so, he head-butted Tyson, producing a large cut over the latter's right eye (although trainer Ritchie Giachetti believed the injury happened in the first round). Tyson had repeatedly complained about head-butting in the first bout between the two fighters. Upon reviewing replays, referee Mills Lane stated that the headbutts were unintentional and non-punishable.

As the third round was about to begin, Tyson came out of his corner without his mouthpiece. Lane ordered Tyson back to his corner to insert it. Tyson inserted his mouthpiece, got back into position, and the match resumed. Tyson began the third round with a furious attack. With forty seconds remaining in the round, Holyfield got Tyson in a clinch, and Tyson rolled his head above Holyfield's shoulder and bit Holyfield on his right ear. A one-inch piece of cartilage was torn from the top of Holyfield’s ear, which Tyson spat out onto the ring apron.
