Maybe Jerry needs to go through one of those concussion protocol tests now. 

When any professional sports team goes on the road, they try to show some love to the fans in enemy territory. Maybe signing some autographs or taking some photos. Even the Dallas Cowboys owner got in on the fun of the autograph signing. Fans were throwing stuff down for him to sign.

It looked like mostly hats, but one fan had a full blown replica helmet with him. He tossed it at Jerry and hit him right in the neck. It's hard to tell from the video if Jerry saw it coming. Looks like he took the hit like a champ. It looks like he even ended up signing the helmet anyway.
