“Given the enthusiastic response to vaccination requirements, the team also announced that, should they advance past round one, tickets will be sold exclusively to fully-vaccinated individuals.”

“The energy our Knicks fans have brought to the playoffs has been incredible, proving there’s nothing more exciting than Knicks basketball at the Garden,” said David Hopkinson, EVP, MSG Sports and President, Team Business Operations in a statement. “It’s moments like this that show us what’s possible if everyone gets vaccinated–we’ll all be able to get back to doing what we love–and that definitely includes being together to cheer on the Knicks at Madison Square Garden.”

According to the team’s statement, vaccinated fans have made up over 90% of those in attendance at The Garden during the first round series against the Hawks.
