Uruguay striker Luis Suarez has been suspended from all football-related activity for four months for biting Italy defender Giorgio Chiellini.
The 27-year-old Liverpool player has also been banned for nine international matches, ruling him out of the rest of the 2014 Fifa World Cup.
It means he will miss the first nine games of the Premier League season.
The incident occurred during Tuesday’s 2014 Fifa World Cup Group D game, which Uruguay won to qualify for the last 16.
Uruguay have three days to appeal against the decision.
The previous record World Cup ban was the eight-match suspension handed to Italy defender Mauro Tassotti in 1994.
Tassotti was punished for elbowing Spain’s Luis Enrique in the face in the 1994 USA World Cup quarter-final and banned retrospectively on video evidence after Hungarian referee Sandor Puhl missed the original incident.
