Simon Davey has left Barnsley as manager.
The Tykes have had a torrid start to the season and currently sit bottom of the Coca-Cola Championship, having picked up just one point from their opening five games.
Their poor form continued on Saturday when they suffered a 3-1 home defeat to Reading at Oakwell and the two parties have agreed to go their separate ways.
A club statement read: "It is with regret that Barnsley Football Club and first team manager Simon Davey have tonight mutually agreed to part company.
"We would like to place on record our sincere thanks for all the hard work Simon has put in during his two-and-a-half tenure as manager and wish him every success in the future."
