Pulis had been watching the game between Rovers and Bolton and left early because of the abuse Kean was getting, but on Monday he said that the atmosphere had certainly improved by the Rovers fans concentrating on getting behind their side.
He said: "I thought the Blackburn supporters were brilliant today. They stuck with their team all the way through, and they need to do that.
"If they've got problems with Steve or the owners, then do it in other ways, don't turn up to a game and take it out on the manager and the people who run the football club because it has an effect on the players."
