FIFA banned Uruguay players Fernando Muslera and José María Giménez for four games each on Friday for aggressively confronting match officials when the team was eliminated from the World Cup last month.
Veterans Edinson Cavani and Diego Godín 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.
The Uruguayan soccer federation was also fined 50,000 Swiss francs ($54,000) and must close some of its stadium for one home game.
FIFA disciplinary judges ruled the federation “was responsible for the discriminatory behavior of its supporters as well as for the misconduct, offensive behavior and violation of the principles of fair play” by players.
Uruguay players confronted German referee Daniel Siebert after the final whistle at Al Janoub Stadium.
They believed Uruguay should been awarded a penalty kick in stoppage time. One more goal scored would have sent Uruguay to the round of 16 instead of South Korea.
South Korea advanced instead and created one of the most memorable images of the World Cup.
As Uruguay and Ghana played out stoppage time across the city in Doha, South Korean players and staff gathered in the center circle after their 2-1 win over Portugal to watch on cellphones as their rivals played and waited to discover who would advance as runner-up in Group H.
Cavani, Godín and goalkeeper Muslera were each playing at their fourth World Cup and Giménez was at his third.
Uruguay has not yet announced its opponents for games in the late March international break.
Four Uruguay players have received suspensions after they confronted the referee at the end of their World Cup game against Ghana last month.
Fernando Muslera and Jose Maria Gimenez have received four-match bans while Diego Godin and Edinson Cavani have been suspended for one game each.
Uruguay’s players had been angered after they were not awarded a penalty.
They won the game on 2 December 2-1 but were knocked out of the World Cup on goals scored.
Instead, South Korea progressed by virtue of scoring one more goal than Uruguay after they beat Portugal 2-1.
The four Uruguay players will also have to carry out football-related community service, and will pay fines of up to 20,000 Swiss francs (£17,500).
The Uruguayan Football Association was also fined 50,000 Swiss francs (£44,000) for the behaviour of supporters and team members, Fifa said, while Uruguay will have to partially close their stadium for their next international match as hosts.
