According to Jon Rothstein, Diallo will declare and sign with an agent, ending his UK career.
Diallo had a mixed redshirt freshman season. He averaged an even 10 points per game, along with 3.6 rebounds and 1.2 assists per game. He shot 43 percent from the field and 34 percent from 3-point range.
Diallo attracted national attention when he had his best game of the year against the Buffalo Bulls in the NCAA Tournament, scoring 22 points, bringing in eight rebounds and blocking two shots.
Diallo likely hurt his draft stock by returning to UK for his redshirt freshman season.
