Since April 18th, the City of Philadelphia did put back the mask mandate because of the rapid increase of COVID cases. It meant that if you wanted to go see the Flyers or the 76ers at the Wells Fargo Center, you had to put a mask on your face.
However, this mandate has already been dropped by the city. Why? The cases are dropping. Masks are still strongly recommended.
The Flyers have still two games left at home before the end of the season against the Pittsburgh Penguins on Sunday and the Ottawa Senators next Friday.
