The NCAA has long believed to have been investigating Labissiere, specifically his relationship with his guardian, Gerald Hamilton.
UK has not confirmed the report. Head coach John Calipari has previously said he isn't worried, and that everyone would have to wait and see who takes the court for the team's first game Nov. 13 at Rupp Arena.
The 6-foot-11-inch Haitian freshman is expected to start for the Wildcats this season, who are ranked No. 1 in the preseason Coaches Poll.
DraftExpress lists Labissiere as the projected No. 1 overall draft pick in the 2016 NBA Draft.
