Zion Williamson has committed to Duke.

Williamson is widely considered the second best prospect in the incoming class of 2018.

Williamson will join top overall recruit R.J. Barrett at Duke.

Billy Preston has signed with BC Igokea, a European club located in Bosnia and Herzegovina.

Preston had not appeared in a regular season game this season for Kansas as the school investigates the "financial picture" of a car Preston was driving in a single-car accident from early November.

Preston was a top-20 recruit in the incoming 2017 class.
