Sheffield Wednesday have parted company with manager Paul Sturrock following a miserable start to the season which has left the South Yorkshire side 21st in the Championship.
On Tuesday evening the Owls slumped to a 4-0 defeat at Colchester and that result appeared to be the last straw for club officials who have acted quickly in an attempt to stop the rot.
"Our league position says it all," chairman Dave Allen told the club's official website.
"However, the chairman and directors would like to place on record our thanks to Paul for his efforts.
"No one will forget that wonderful day we all had at Cardiff when we won the play-offs and were subsequently promoted to the Championship.
"Unfortunately, in spite of strengthening the squad this year, we have not made the desired progress and, to that end, we need a change in the coaching staff."
Sturrock arrived at Hillsborough in September 2004 and after steering Wednesday to promotion from League One via the play-offs in his first season, successfully staved off relegation in a difficult last term.
