MIKE TYSON
Probably the most infamous sporting bite occurred in the boxing ring, when Mike Tyson challenged Evander Holyfield for the world heavyweight title in 1997.
Tyson bit off a chunk of Holyfield's left ear and spat it on the floor prompting the referee to call time out. He later claimed he had been aggravated by Holyfield's continual head-butting, but he was still disqualified from the competition.
PENALTY: Boxing licence revoked and $3 million (£2m) fine.
FRANCISCO GALLARDO
In 2001, Sevilla striker Francisco Gallardo got a little carried away during a goal celebrating, biting his own team-mate José Antonio Reyes in a sensitive area.
PENALTY: Life-long ridicule.
