Former Michigan State football player Keith Mumphery was expelled last year from his graduate studies program and banned from campus for violating the university's relationship violence and sexual misconduct policy, according to MSU Police documents obtained via the Freedom of Information Act by the Free Press.

The March 2015 incident involving the current Houston Texans wide receiver is the third case of alleged sexual misconduct among current and former MSU football players in the past three years. Only one of them – an April incident involving Auston Robertson – has led to charges, while another case remains ongoing.

Mumphery was accused of sexually assaulting a student in her MSU dorm room on March 17, 2015. The woman reported it to MSU Police that night shortly after the incident. According to the campus police report, the two met a few months before the incident on an online dating site, agreeing to meet at her dorm room weeks later. The report details conflicting accounts of who was the aggressor and whether elements of their sexual behavior were consensual.

Mumphery had completed his MSU playing career at the time of the incident and worked out the next day for NFL representatives during the Spartans' pro day at the Duffy Daugherty Football Building. Houston selected Mumphery in the fifth round of the 2015 NFL draft on May 2 that year.
