The NCAA determined that prior to his enrollment at WVU, Gerun played three games on a professional team in Ukraine during the 2011 season which is contrary to NCAA regulations governing amateurism.
A 6-foot-10 forward from Dnipropetrovsk, Ukraine, Gerun led Ukraine in scoring (18.2), rebounding (11.1) and blocks (2.1) at the 2011 under-18 European Championships.
Gerun was previously determined to be a sophomore in terms of eligibility by the NCAA.
