The Youngstown State football team is wearing Guardian Caps during summer camp.

The players have had them on for a week and can feel their worthiness.

"My first hit at practice with on, I was like where have these been," said defensive end Hunter Allen. "They truly are a difference maker and helps keep us healthy."

The NFL will allow the caps to be worn during the regular season.

"It's just an extra precaution," said coach Doug Phillips. "Anything that we can do to add to safety we're going to do."
