The NCAA ruled Nov. 4 the Belgium native was ineligible, but Wisconsin filed a waiver citing ''factors outside of Van Vliet's control.'' The school received word Tuesday that appeal had been denied.
Vliet, a 6-foot-11 freshman, was expected to add depth to a Badgers frontline that lost Frank Kaminsky, Sam Dekker and Duje Dukan from a squad that reached last year's national championship game.
The school said NCAA rules allow student-athletes one year to enroll in college following their high school graduation or expected graduation date. But Van Vliet, 20, played as an amateur outside that window. In addition to sitting out this season, he will only have three years of eligibility remaining.
