"Personal criticism of this nature is never acceptable and the players are shocked that someone from within their club has seen fit to make such comments," it read.
"Whilst accepting that anyone can have an opinion on football, someone in such a position of responsibility should be more mindful of the comments he makes, particularly when you consider what a valuable member of the team Morten is and the great contribution he has made and continues to make to Blackburn Rovers and Norway."
New signing Danny Murphy added: "Speaking on behalf of all the players, I think everybody was hugely disappointed with what was said.
"The lads certainly weren't happy about it. We're together, we stand by each other's side and we back the manager.
"We're at the start of what will hopefully be a successful season. We're looking forward to getting going and that spoiled it a bit.
"I think it's been dealt with, by the players anyway. We've made our line in the sand and we'll move on. Dwelling on negative situations for too long won't benefit us."
One of Singh's comments at the meeting was that
Kean would be sacked
if Rovers lost three consecutive games early in the season.
But Kean says he has had positive talks with club owners Venky's about his future at Ewood Park.
"I've spoken with Mrs Desai at length and we had some great conversations at the end of last season," he added.
"She's been very supportive of us building a squad. Everybody wants us to succeed, none more so than me and the players."
Blackburn go to Ipswich for their first game of the season on Saturday.
