Howard University has prevented some of its athletes from competing while the school investigates what it said Wednesday were possible violations of NCAA rules.

In a statement issued by university spokesperson Kerry-Ann Hamilton, the school said it "temporarily withheld a number of student-athletes from competition as a self-imposed action. Most teams will compete as scheduled. We are working diligently to fully resolve this matter as quickly as possible.

"In order to protect the integrity of this review, we are unable to share additional details at this time."

The statement didn't say which sports or how many athletes were affected, or what rules might have been breached.

There are spring sport teams that will compete as scheduled this week.

Howard's sports information director, Ed Hill, did not reply to repeated requests for comment. NCAA spokesman Erik Christianson declined a request for comment, referring questions to Howard.

Founded in 1867, Howard is a private university and historically black school with about 10,500 students. Its football team has two winning seasons in the past 13 years; its men's basketball team hasn't had a winning season since 2001-02; its women's basketball team lost in the first round of the WNIT this season.

Howard competes in the Mid-Eastern Athletic Conference.
