Gary Bowyer has become the first manager in England's top four divisions to step down from his position, having departed Blackpool after just one match.
The reasons behind the 47-year-old's departure are unknown, although he recently claimed that he was unhappy at losing the core of his squad after guiding the club to a top-half finish last term.
"It has been a pleasure to manage Blackpool Football Club over the past two years," Bowyer said in a statement published on the Seasiders' official website.
"I'm extremely grateful to the board for giving me the opportunity to manage such a historic football club and I would like to thank the supporters, your unbelievable passion and support of both the team and myself will stay with me forever."
Terry McPhillips will step up from his position as assistant manager to take charge of next weekend's home match against Portsmouth.
