George Perles has resigned as a member of Michigan State University's governing board after nearly 12 years, citing his age and health.
Perles was a former Michigan State football coach and athletic director before winning election as a trustee in 2006. A Democrat, he was re-elected to an eight-year term in 2014.
The 84-year-old Perles has Parkinson's disease, and he says the consequences "continue to grow." In a statement dated Wednesday, he says he and wife Sally "need to make our life smaller as we age and consider our quality of life."
In September, a woman alleged that Perles covered up a rape allegation against sports doctor Larry Nassar when Perles was athletic director in 1992. Pat Perles called it a "fabrication" and insisted his father had never met the woman, who was a 17-year-old field hockey player at the time.
