Nigel Adkins is to leave his role as ChampionshipHull City head coach after 18 months in charge of the Championship club.
BBC Humberside understands Adkins had agreed a salary and budget but rejected the offer of a new deal due to 'other contractual terms'.
"After much careful consideration I have decided that our futures are not aligned," the 54-year-old said in a statement on social media.
Adkins and his assistant Andy Crosby will leave on 30 June and Hull say the search for his successor "is already under way".
