ORCHARD PARK, N.Y. — The countdown is on, as it is just four days until the Bills play the Indianapolis Colts in the Wildcard match-up at Bills Stadium. 

The fans that were lucky enough to score a ticket need to get a COVID-19 test before the game.

Testing must be done at the stadium.

Erie County leaders say what happens Saturday will have an impact on future games.

"We are very concerned about people gathering. As the governor noted and as I noted last week, if there are people tailgating it's probably going to result in the state not allowing fans in the second game, after we beat the Colts. So we're telling folks don't blow it for others," said Erie County Executive Mark Poloncarz. 

Contact tracing will be done after the game.
