The NCAA cited what it calls "the most egregious lack of institutional control ever seen" by its Division II investigative committee.
The penalties include five years of probation, a cancellation of seasons for certain sports, a one-year postseason ban in all sports, forfeiture of wins in select sports, a reduction of scholarships and a reduction in recruiting activities.
Most of the violations occurred from 2000-04, and some of the harshest penalties have already been self-implemented by the school.
The Division II Committee on Infractions found that the university allowed 248 athletes and two prospective athletes to practice or compete while ineligible. The committee said the university acknowledged it did not have policies in place to properly monitor its student-athletes and failed to accurately report information relating to violations.
