The NFL is tightening stadium security for all teams starting this preseason, limiting the size and type of bags fans can bring to the game. 

"Our fans deserve to be in a safe and secure environment," says Jeffrey Miller, the NFL's chief security officer. "Public safety is our top priority. This will make the job of checking items much more efficient and effective. We will be able to deliver a better and quicker experience at the gates and also provide a safer environment."

Banned items now include purses larger than a clutch, coolers, briefcases, backpacks, fanny packs, cinch bags, seat cushions, luggage, computer bags, and camera bags.
   
Fans with those items will not be allowed to enter an NFL stadium.
   
Besides the clutch-size purse, the NFL's new rules only allow for clear plastic, vinyl or PVC bags no larger than 12 inches by 6 inches by 12 inches or 1-gallon clear plastic freezer bags.

However, medically necessary items are allowed unconditionally. Binoculars, cameras, and smart phones will also be allowed inside.
