Coventry have parted company with manager Peter Reid by mutual consent after only eight months.
The Sky Blues won just one of their last eight games under Reid
The Sky Blues have won only 10 out of 31 games under former Manchester City, Sunderland and Leeds boss Reid, who took over at the end of last season.
Four straight defeats have left the team 20th in the table and chairman Mike McGinnity said: "Peter told me the best thing was to go our separate ways.
"I brought Peter in because of his experience but we haven't had luck."
First-team coach Adrian Heath will take charge for Saturday's FA Cup third-round tie with Crewe.
The final straw for Reid came when fans chanted for his dismissal following the 2-1 home defeat by Leeds.
But McGinnity insists criticism of the former England midfielder has been harsh.
"We as a club were underachieving, don't put all the blame on Peter Reid, the players are responsible too," he added.
"You've got to look at the restraints he was working under here."
