Citing what it called “the most egregious lack of institutional control ever seen” by its Division II investigative committee, the NCAA on Wednesday levied numerous sanctions on the University of the District of Columbia. Among the penalties — including some the school already imposed on itself — are 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. The NCAA Division II Committee on Infractions found that the university allowed 248 athletes and two prospective athletes to practice or compete while ineligible from the 2000-01 through the 2003-04 academic years.
