NEW YORK (AP) — The NFL says it has "enhanced" its pat-down procedure for fans entering stadiums to improve safety.
The league has asked all 32 teams to have stadium security search fans from the ankles to the knees. Previously, fans were patted down from the waist up for banned items such as alcohol and weapons.
Last week, a man was arrested for using an illegal stun gun at Sunday night's Dallas Cowboys-New York Jets game.
NFL spokesman Brian McCarthy said Friday the "enhanced security procedures" are not a result of any specific threat, but the league is "always refining and improving" security.
He says the checks, which began before last week's season-opening games, will take longer, and encourages fans to arrive early.
