Bite Fight: June 28, 1997
It was the rematch between Mike Tyson and Evander Holyfield at the MGM Grand Garden Arena in Las Vegas, Nevada.
In the second round, Holyfield ducked under a right from Tyson. In doing so, he head-butted Tyson, opening a large cut over Tyson's right eye. Tyson had complained about head-butting in the first bout between the two fighters. Upon reviewing replays, referee Mills Lane stated the headbutts were unintentional and nonpunishable.
In the third round, Tyson lost his mind. He bit a chunk out of Holyfield’s right ear and then spat it onto the canvas.
The fight was delayed for several minutes as Lane debated what to do. Lane's original decision was to disqualify Tyson, but after the ringside doctor determined that Holyfield was able to continue despite the bite, Lane announced a two point deduction from Tyson and the fight would continue.
But Tyson proceeded to bite Holyfield’s other ear.
Tyson was disqualified from the match, fined $3,000,000 and was ordered to serve a period of community service. After a year and an appeal in court, Tyson's license was reinstated.
