Correct, and it was the word "Fighting" they didn't approve of being used with their name.If I remember correctly (from the Great Native American Nickname Purge from several years ago now which cost Illinois their logo and mascot and other schools their nicknames), unlike with Florida State and Central Michigan where the Seminoles and Chippewas respectively approved the use of their names with said institutions, I don't think the Sioux ever approved the use of their name.
