Tom Izzo’s time as a tour guide for the Iron Mountain High School basketball team didn’t sit well with the NCAA.

Michigan State basketball committed a secondary NCAA violation, according to MSU records obtained by the Detroit Free Press.

Before the Mountaineers played in this past season’s Division 3 state semifinals at the Breslin Center in East Lansing, Izzo committed the violation by taking his alma mater’s high school team on a tour of Michigan State’s locker room and practice facility on March 13. He also permitted the team to watch the Spartans practice.

The act, according to the Free Press, was classified as a violation because high school players are not allowed to tour facilities if they are present for competition-related activities.

The violation was classified as secondary in nature and there was no punishment levied because of the circumstances.

Michigan State is not recruiting any of Iron Mountain’s players, and the university’s office of compliance services stated it would have applied for a waiver had it known ahead of time Izzo wanted to give his former high school a tour.

In one of Powers North Central’s recent state tournament appearances, Izzo visited with Jets’ coaches and players at the Spartans’ facilities. But that did not result in an NCAA violation.
