Harry Giles, Scout's No. 1 player and the favorite to be the top pick in the 2017 NBA Draft, partially tore the ACL in his right knee, multiple sources told Scout on Thursday.
The injury occurred during the first two minutes of Mouth of Wilson (Va.) Oak Hill's season opener on Tuesday.
Giles, a 6-foot-10 power forward, had previously recovered from tearing the ACL and MCL in his left knee during the summer between his freshman and sophomore season.
Giles is on the brink of announcing his college decision. His finalists include Duke, Kansas, Kentucky and Wake Forest. He's taken official visits to all four schools, including his final trip to Duke this past weekend.
A native of Winston-Salem, Giles transferred from Wesleyan Christian to Mouth of Wilson (Va.) Oak Hill Academy for his senior season.
Giles has won Gold Medals with USA Basketball in the 2013 FIBA Americas U16 Championship, the 2014 FIBA U17 World Championship and most recently in the FIBA U19 World Championship.
With the U19 team this past summer, Giles led USA in both scoring and rebounding with 14 points and 10.6 rebounds a game.
