FIFA banned Uruguay players Fernando Muslera and José Maria Gimenez for four games each on Friday for aggressively confronting match officials when the team was eliminated from the 2022 FIFA World Cup.
Veterans Edinson Cavani and Diego Godin must also serve one-game bans when Uruguay next plays, FIFA said in disciplinary verdicts.
The players must all carry out community service on a soccer project and pay fines of up to 20,000 Swiss francs ($21,600), FIFA said.
Disorder flared when Uruguay failed to advance to the round of 16 in Qatar despite beating Ghana 2-0 in its final group-stage game on Dec. 2.

FIFA disciplinary judges ruled the federation "was responsible for the discriminatory behaviour of its supporters as well as for the misconduct, offensive behaviour and violation of the principles of fair play" by players.
