When packing up and heading to AT&T Stadium in Arlington for the TCU season opener against LSU Saturday night, be careful which bag you bring.

The National Football League announced a new bag policy in August that affects security measures at the game Saturday. Fans will not be allowed to bring many types of bags and purses into the stadium, according to the Dallas Cowboys' website.

A new policy enforced at AT&T Stadium prohibits "all purses, bags or containers larger than a small clutch bag, coolers, briefcases, backpacks, fanny packs, cinch bags, luggage of any kind, computer bags and camera bags."

The Committee on Stadium Security and Fan Conduct of the NFL agreed unanimously in May to limit bags in NFL stadiums in order to enhance public safety and improve stadium entrance efficiency.

According to committee documents, the Boston Marathon bombings in April were a factor in the decision to adjust the policy.

Only small clutch purses will be allowed through the entrance. The other options are a clear plastic tote bag measuring 12 inches by 6 inches by 12 inches or a clear, re-sealable plastic storage bag.

The small clutch purse option must be the size of a hand and no larger than 5.5 inches by 8.5 inches.

According to the NFL website, "fans carrying bags that do not meet the criteria will be turned away from the stadium well before they reach the gates."

The instructions on the AT&T Stadium website state that "all bags are subject to inspection upon entry and are subject to additional inspections within the stadium."
