Coach Greg Graham said freshmen Larry Davidson and Darius Harper and junior Mattias Johansson will no longer be members of the team. Also, guard Bryan Defares has been suspended for Friday's season opener against Portland.
Davidson, a 6-foot-10 forward from Terrigal, New South Wales, Australia, redshirted last season after having surgery on both knees. He is returning home because further knee problems have curtailed his career.
Harper, a 6-foot-1 freshman guard, is leaving for personal reasons which were not revealed. He will stay at the school through the fall semester.
Johansson, a 7-foot-0 center, has been declared ineligible after it was learned he violated NCAA rules by playing in a professional league in Europe. He signed with Boise State in the spring of 2003.
Defares, a 6-foot-4 senior, has been suspended one game for playing in a non-sanctioned summer league game last summer.
