If you are one of the thousands heading to Arrowhead Stadium Friday for the Chiefs 2013 preseason home opener, there is a new policy you should be aware of.

In an effort to increase security only clear plastic, vinyl or PVC bags are allowed. The bags cannot be larger than 12” x 6” x 12”.

One gallon clear plastic zip sealed bags are allowed. Small clutch bags approximately the size of a human hand with or without a strap may be brought in along with one of the clear bag options.

The Chiefs organization said exceptions will only apply to medical necessities that are inspected at Gate D, Gate F, Tower Gate and Founder’s Plaza Gate.

Season ticket holders are eligible for a free bag for every four seats and can pick them up on game day with a voucher at Gate D, Gate F, Sprint Gate or the Hy-Vee Gate prior to kick off.

Vouchers can be printed off here.
