Barnsley boss Paul Hart has agreed to leave the club by mutual consent.
Hart accepted a severance deal
The 51-year-old accepted a severance package with the League One club after negotiations on Friday.
And first-team coach Andy Ritchie will now take temporary charge as the South Yorkshire outfit begin their search for a permanent replacement.
"Amicable discussions have been taking place about the best way forward and
we feel this is the best solution," said club chairman Gordon Shepherd.
A poor Barnsley recent run - just two wins in their last 13 league matches - prompted the new board at Oakwell to opt for a change.
"I would like to place on record my thanks to the players, coaching staff and
supporters during my time at the club," Hart said in a statement.
"I wish everyone involved the best of luck in their efforts to gain a play-off place this season and do wish them continued success for years to come."
