FIFA opted to punish Luis Suarez heavily for biting an opponent in a World Cup match because the Uruguayan showed no remorse for the incident and previous bans had not changed his behavior, according to an internal FIFA document.

Suarez was hit on Thursday with a nine-game suspension on playing competitive matches for Uruguay and a four-month ban from any soccer-related activity, a record punishment for a player at a World Cup.

The decision ended the involvement in the tournament in Brazil of one of the sport's best players and prompted fury in the South American nation at the scale of the punishment for Suarez who was given a hero's welcome on his return.
