MANHATTAN, Kan. (AP) — Kansas State students will have to sign a sportsmanship pledge before they can pick up their tickets for sporting events this year. The pledge requires students to refrain from using profanity and inappropriate chants and to show respect for all athletes, coaches, fans and officials. The Wichita Eagle reports that the sportsmanship pledge is the first in the Big 12 Conference. The pledge comes after problems arose during a Kansas State-Kansas basketball game last season in Manhattan. Students chanted inappropriate language during the game and stormed the court afterward, and one student seemed to intentionally bump a Kansas player. Kansas State officials say students who behave badly during games will be dealt with on a case-by-case basis.
