London - Steve Kean has been backed by the League Managers' Association (LMA) after the Blackburn boss was subjected to another torrent of abuse during his side's 2-1 defeat against Bolton.
Kean has been forced to endure increasingly aggressive taunts from Rovers fans angry at their club's poor form in the Premier League this season and the abuse reached new levels at Ewood Park on Tuesday.
A large section of the Rovers support have called on Blackburn's Indian owners Venky's to sack Kean and even the local newspaper demanded his dismissal this week.
The ill-feeling spilled over completely once Mark Davies had scored Bolton's opener on Tuesday as Blackburn slumped to a defeat that left them bottom of the table.
It continued throughout the match and long after the final whistle as hundreds attended a demonstration against Kean outside the stadium.
However, Kean can at least rely on the support of the English LMA, who have stepped in, calling the abuse "unacceptable" and "well beyond the mark".
"When results continue to be bad on the field fans who give up their hard-earned money to support their club have a right to voice their opinion," said the LMA.
"However, the aggression and abuse levelled at Steve over recent weeks has stepped well beyond the mark and is as unacceptable in football as it would be in any other profession.
"It is to Steve's significant credit that he has shouldered this continued onslaught with dignity and professionalism and has continued to work with his players to try and improve results on the pitch."
While supportive of Kean, the LMA also believe it is important that the Rao family, who own Rovers, start to put in more appearances at Ewood Park to show the unhappy fans that they are aware of their frustrations and are taking charge of the situation.
"Owners of clubs such as Blackburn Rovers rely on the support and the relationships they build with their fans and their local community," the organisation said.
"As new owners, the Venky's should build relationships, develop trust with their fans and communicate their vision on a regular basis in an open and visible way."
