University of Central Florida president John Hitt pledged to fully cooperate with NCAA investigators after receiving a letter of inquiry about possible violations the football and basketball programs.
The probe likely stems from the recruitment of basketball recruits Michael Chandler and Kevin Ware, and that of football recruit DeMarcus Smith.
None of the three athletes the investigation could focus on have begun taking classes at the school.
Ware, from Conyers, Ga., was released from a national letter of intent he signed with Tennessee after coach Bruce Pearl was fired. He subsequently signed a grant-in-aid with UCF in April. But he then backed out of his commitment to the Knights.
The school has retained Mike Glazier, head of the Collegiate Sports Practice Group of the Bond, Schoeneck & King law firm, to lead the investigation.
