It is a sign of the times now.
T.D. Garden in Boston will be requiring all fans, performers and staff to be vaccinated for coronavirus.
All fans 12-years-old and over must show proof of vaccination or a negative COVID test to attend, perform or work at the arena.
The rules will apply to all Celtics and Bruins games, along with concerts and other events at the arena.
Garden officials say the rules were imposed to allow the facility to continue operating while keeping everyone safe.
The new protocol begins next Thursday night when the Bruins open up their home preseason.
