Harry Giles has committed to Duke, picking the Blue Devils over Kentucky, Kansas and Wake Forest.
Giles suffered a partially torn right ACL this week and had previously torn the ACL in his left knee.
Giles is rated as the No. 1 recruit in the 2016 class by ESPN.
Giles will have the chance to play with Jayson Tatum, who is ESPN's No. 2 recruit.
"We were roommates in USA Basketball this past season," Tatum told ESPN. "When you spend over 30 days together, you either grow closer or apart. We got closer."
Jeff Capel was key in the recruitment of Giles.
"Jeff built a great relationship with Harry and that was key," Oak Hill assistant coach Cory Alexander said.
