The Chargers could have kept their “home” game against the Chiefs at home. They decided not to.
The league reportedly has picked the Chiefs to be the Week 1 Friday night opponent for the Chargers in Brazil. The Chiefs game was not one of the two home games that Chargers chose to protect.
As recently explained by Ben Fischer and Austin Karp of Sports Business Journal, teams exporting home games to the international series can protect up to two games. The Chargers, per the report, did not protect any of their three AFC West home games.
