In September 2019, Self and the Kansas program were served a Notice of Allegations by the NCAA for five Level 1 violations, a head coach responsibility charge against Self personally, and a lack of institutional control charge against the University of Kansas. Self's individual punishments could include a suspension or an effective ban from college basketball for several years or more (a "show cause" penalty against any program looking to hire Self) as well as a suspension. The team faces a postseason ban which would end their record 31 consecutive NCAA Tournament appearance streak as well as a loss of scholarships. Self had denied throughout the investigation that the Kansas coaching staff knew Adidas was paying recruits to go there, but according to a 2021 court filing one of Self's assistants was recorded by federal agents discussing logistics of player payments and stating plainly that he knew Kansas was violating NCAA rules.
