The NCAA said Michigan State University did not commit any “substantial violations” of NCAA legislation in its handling of the allegations against disgraced former athletics doctor Larry Nassar. Jonathan F. Duncan, the NCAA’s vice president of enforcement, wrote “that it does not appear there is a need for further inquiry,” in a letter to Bill Beekman, MSU’s athletic director. Hundreds of athletes have accused Nassar of sexual assault and a former MSU gymnastics coach was charged for allegedly misleading investigators about the abuse last week. “We welcome closure in regards to the NCAA inquiry,” Beekman said in a statement. “MSU cooperated fully with the inquiry over the past several months.” Mark Hollis, who was the MSU athletic director at the time, received a letter of inquiry from the NCAA in January about the Nassar situation. Three days later, Hollis resigned amid a bombshell ESPN report that prompted the NCAA to launch a second probe.
