Coventry City have sacked manager Steven Pressley after almost two years in charge of the Sky Blues.
Pressley's assistant Neil MacFarlane and professional development coach Dave Hockaday, who arrived only three weeks ago, have been put in temporary charge.
Coventry have slipped into the League One relegation zone, having failed to win any of their last seven matches.
"It was very difficult from a personal and professional point of view," said chief executive Steve Waggott.
"But results over recent weeks and months, and our precarious position in the league table, means that a change of direction at first team level is needed."
The final game of 41-year-old Pressley's 100 in charge came at Bramall Lane on Saturday when, despite playing against 10 men for most of the game, City allowed Sheffield United to score twice in the final 11 minutes to earn a 2-2 draw.
The former Rangers, Dundee United, Hearts, Celtic and Scotland centre-half left Falkirk to take over at City in March 2013 following the resignation of Sky Blues predecessor Mark Robins to join Huddersfield.
Pressley was contractually tied to the Sky Blues until 2018, having signed an initial three-and-a-half-year deal before having that extended to a new four-year agreement in September 2014.
The new contract was signed in a mood of euphoria that followed City's return to the Ricoh Arena, but that mood has changed in recent months - and home gates have fallen to below 7,000.
For the majority of his time in charge, Pressley was generally viewed by fans as a popular, engagingly frank character, who motivated his team well in adversity, but had to contend with the distracting backdrop of the club's off-field woes.
As well as twice being docked 10 points as a result of the club's owners Sisu, now rebranded as Otium, going into administration, while fighting against their landlords at the Ricoh Arena, City even underwent an entire season in exile at Northampton.
And they have been made to play second fiddle at their own stadium following confirmation, then the harsh economic reality, of their new landlords Wasps' well-marketed move to the Ricoh Arena.
Since the news broke of rugby union's arrival at the stadium, Coventry have won just four times in 24 League One games, as well as suffering the embarrassment of losing at home to non-league Worcester City in the FA Cup.
With 15 games of the season to go, City lie 21st, in danger of being relegated to the fourth tier of English football for the first time since 1959.
Three of their next four matches at home, starting with Saturday's visit of second-placed MK Dons, but the state of the Ricoh pitch since Coventry's new landlords came in does not necessarily make that an advantage.
