Argentina players displayed a banner stating "The Malvinas are Argentine" during recent celebrations, referencing the 1982 conflict over the Falkland Islands.
The 74-day war between Argentina and the United Kingdom resulted in the deaths of 255 British servicemen and 649 Argentine personnel.
The UK government has supported calls for an investigation into the incident, reaffirming its position on the sovereignty of the Falkland Islands.
A political leader has urged FIFA to suspend the players involved ahead of Sunday's final against Spain, citing precedent in similar cases.
The appeal referenced UEFA's suspension of two Spanish players who chanted a political slogan during Euro 2024 celebrations.
World Cup regulations explicitly prohibit the display of political messages by players before, during, or after matches.
Argentina previously received a fine from FIFA for displaying the same slogan after a 2014 friendly match.
FIFA is expected to open a disciplinary investigation into the incident following the tournament.
Any sanctions, which could include fines or suspensions, are unlikely to be applied before the final, allowing the players to compete.
Observers note that sporting suspensions are generally reserved for the most serious violations and may be less likely in this case.
