Fergus Connolly, director of performance for Michigan’s football team, was arrested Monday on suspicion of drunken driving.

Detective Lt. Matthew Lige of the Ann Arbor Police Department confirmed the arrest. Connolly has not yet been charged.

“We are waiting for lab results before the investigation can be presented to the prosecutor’s review on potential criminal charges,” Lige wrote in an email to The Detroit News, adding he could not release further details. “The return of the lab results will take several weeks.”

A Michigan official indicated in a statement that the athletic department is aware of the incident.

“We are still awaiting more detailed information before commenting further,” according to the statement.

Connolly, who has a PhD in computer integration-based optimization from the University of Limerick in Ireland, has worked the last two seasons for Michigan football as the director of performance science. Before his arrival at Michigan, he spent two seasons as director of elite performance with the San Francisco 49ers.
