Skal Labissiere has not been cleared to play by the NCAA to play for Kentucky, his guardian said on Wednesday.
Labissiere is expected to be one of the first three picks of the 2016 NBA Draft.
"Not yet," Labissiere's guardian, Gerald Hamilton, told ESPN. "We're just trying to get everything squared away. They are asking a few questions.
"They haven't cleared him, but we're sticking with our faith," he added. "There's no real concern about anything from the Kentucky compliance people."
When asked about the specific reason Labissiere has yet to be cleared, Hamilton told ESPN he did not wish to comment.
Multiple sources told ESPN that the NCAA was looking into Hamilton and his relationship with Labissiere, but Hamilton declined to comment on whether that was the holdup.
