Longtime Portland High football coach Mike Bailey resigned this afternoon.

Mike McCullum, the second-year athletic director at Portland High, confirmed that he received Bailey’s resignation but declined to give an explanation.

“I can confirm that he resigned,” McCullum said. “The rest of it is a personnel matter that I’m not going to discuss.”

Attempts to reach Bailey, who remains a science teacher in the Portland school system, were unsuccessful.

Bailey is the longest serving football coach in Portland High history, having taken over the program in 1986 after five years as an assistant. A 1973 graduate of Deering High, Bailey compiled a record of 152-116 that included two Western Maine titles and the 2002 Class A state championship.
