Watch Now: Report: NFL Optimistic About 2020 Season Despite Positive Covid-19 Tests (2:20)

The NFL is optimistic the 2020 season will go on as scheduled despite an ongoing COVID-19 pandemic that's disrupted the entire offseason program and seen a recent surge in positive player diagnoses. Even if the regular season does kick off in September, however, countless teams are already preparing to operate with half-filled or even empty stadiums, with some offering to postpone season tickets and others anticipating zero fan presence throughout the fall.

With so much uncertainty surrounding what game days will look like, assuming the 2020 season happens, here's an overview of the stadium setup across the league.
