The Chiefs have banned fans from wearing headdresses and face paint that "is styled in a way that references or appropriates American Indian cultures," the team announced Thursday.
The team announced several new policies Thursday, citing recent conversations with the American Indian Community Working Group.
Kansas City also said it is "engaged in a thorough review process of the Arrowhead Chop" and is "exploring all options for a modified engagement moment from the Drum Deck."
The changes made by the Chiefs come just over a month after the Washington NFL team removed its nickname.
