The NCAA has placed Texas A&M University at Corpus Christi on a four-year probation for violating several rules in its treatment of international athletes.

The NCAA also accused the university’s former athletics director of unethical conduct.

The allegations centered on a female volleyball player, a male tennis player, and a male prospective basketball player. The NCAA alleged the university allowed the volleyball player to compete for a sixth season, one year beyond her eligibility. The association also asserted that the university gave the tennis player $1,500 in athletics aid when he was not qualified to compete — and when the athletics department discovered the violation, it refused to declare the athlete ineligible.

The prospective basketball player, meanwhile, was given free lodging and transportation in violation of NCAA recruiting rules.

In addition to the four years of probation, the NCAA reduced the number of scholarships the university may offer in volleyball and tennis for the next two academic years, and barred both teams from participating in postseason play next year. The university could not be reached for comment today. —Libby Sander
