The World Cup final between Argentina and Spain at Met Life Stadium in East Rutherford, New Jersey, remains on schedule for Sunday despite air quality warnings from Canadian wildfires, sources told ESPN. Health alerts were issued in New York and New Jersey, and an MLS game at Soldier Field was postponed Thursday, but FIFA is not concerned as forecasts show improvement.

The National Weather Service reported smoke lingering but less intense Friday, with potential thickening overnight into Saturday. New York's Office of Emergency Management rated air quality "unhealthy for everyone" Friday, down from "very unhealthy" Thursday. Previous World Cup weather delays included England vs. Mexico and France vs. Iraq matches.

Argentina seeks a second consecutive World Cup title after beating France in the last final, while Spain aims for its second trophy since 2010. The third-place playoff between England and France takes place Saturday in Miami. The Golden Boot race remains tight: Lionel Messi and Kylian Mbappé are tied at eight goals, with Ousmane Dembélé and Mikel Oyarzabal on five each. Goals in the third-place match count toward totals.
