FIFA says it is studying a protest from the Costa Rica soccer federation, which wants a World Cup qualifier against the United States replayed after losing 1-0 in a snowstorm.
FIFA says its administration "will now analyze the content of the letter and next steps will be determined in due course."
Costa Rica says players' "physical integrity" was affected, "ball movement became impossible" and field markings were not visible in Friday's game. It urged FIFA to punish match officials, including referee Joel Aguilar of El Salvador.
The protest must meet specific requirements stated in the 2014 World Cup Regulations.
One clause says that when a field becomes unplayable, the protesting team's captain "shall immediately lodge a protest with the referee in the presence of the captain of the opposing team."
