Argentina's Leandro Paredes has been banned from playing for Argentina for 10 matches.
Argentina defender Nahuel Molina was also handed a seven-match ban, while Thiago Almada was banned for one.
The ban essentially wipes out a calendar year of national representation for Paredes.
FIFA banned three Argentina players overnight, including a 10-match suspension for midfielder Leandro Paredes, for striking Spain opponents after losing the World Cup final.
The ban for Paredes — who grabbed Spain's Eric Garcia by the throat and pushed Gavi to the ground — ranks with the FIFA sanctions for Uruguay forward Luis Suárez in 2014 as among the most severe in World Cup history.
Argentina defender Nahuel Molina was handed a seven-game ban while Thiago Almada was given a one-game suspension. FIFA imposed fines of $US90,000 ($AU125,000) on Paredes and Molina, and $US30,000 for Almada.
The ban for Paredes is effectively a one-year expulsion from the Argentina team as the FIFA calendar for national team schedules includes 10 games through June 2027.
All of those games could be friendlies with no competitive games currently scheduled.

Gavi also was banned for one game, which is a Nations League match for Spain against England at Wembley on September 26.
An Argentina coach, Roberto Ayala, was also handed a three-game ban and a $US30,000 fine.
The Argentine Football Association (AFA) was fined $US110,000 for a range of incidents during the World Cup, including players carrying a political banner about the Falkland Islands after the semifinal win against England, and discriminatory chants by fans.
AFA was also ordered by FIFA to spend $US100,000 on anti-racism projects. Argentina received $US34 million in World Cup prize money from FIFA.
AFA can appeal the longer sanctions and fines to FIFA, and likely after at the Court of Arbitration for Sport.
