The Kansas City Chiefs and Los Angeles Chargers are opening up the 2025 NFL season a long way from home. The AFC West rivals will do battle inside São Paulo, Brazil's Arena Corinthians on Friday, September 5, as part of the NFL's 2025 International Games schedule. In recent years, the NFL has made an effort to expand their reach internationally, which included a game between the Philadelphia Eagles and Green Bay Packers in September 2024 at Arena Corinthians.
