On week 13 of the 2020 NFL season, because of strict COVID-19 restrictions in their home county of Santa Clara, the San Fransisco 49ers played the Buffalo Bills at the State Farm Stadium in Arizona, home of the Cardinals, and will also play their next "home" game against the Washington Football Team there too.
Have there been previous occasions where a regular-season or post-season game (excluding the Super Bowl) has been played at a neutral venue because of particular circumstances that prevent the game being played at the home team's stadium?
