David Cutcliffe won't return for a 15th season as Duke's coach after the school announced a "mutual agreement for separation" on Sunday following the Blue Devils' winless Atlantic Coast Conference record.

The school's announcement came a day after the Blue Devils (3-9, 0-8) closed a three-win season with a 47-10 home loss to Miami. That marked the first winless slate for Duke in league play under Cutcliffe, who transformed the Blue Devils from one of the nation's worst performers into a regular bowl contender and even claimed a division title in the ACC in 2013 before the program slid badly in the past two seasons.

In a statement, Cutcliffe, 67, said the decision came after "some detailed and amiable discussions" with new athletic director Nina King, who took over earlier this year but has worked at Duke since 2008 and handled primary administrative duties for the football program.
