The NFL is taking no chances when it comes to protecting fans attending this week’s draft.

Frank Supovitz, the NFL’s senior vice president of events, said the league is “enhancing security protocols” from Thursday to Sunday at Radio City Music Hall in New York City. That includes additional measures from the league’s own security department and the New York Police Department as well as new guidelines for fans.

Supovitz said fans are being asked to leave backpacks and bulky bags at home. Doors will open an hour earlier than normal “so people can go through the security protocols so they’re not delayed getting into the building.”
