Megson was reported to have become embroiled in a dressing-room bust-up with Jlloyd Samuel during a half-time rant at his players in the 2-1 defeat at Wolves nine days ago.
Megson has confirmed an exchange of views took place with Samuel, but suggestions of anything more than that have been slammed as "scurrilous", with the manager convinced they have come from someone he feels is intent on rocking the boat.
Asked whether the informant was someone within club and whether any disciplinary action would be taken, Megson replied: "That's my problem."
Megson, though, will always make his views known to his players whether it upsets them or not.
"I'm the first to praise the players when they do something right, and the first to have a go when it's not right," said Megson. "I will say what I think, and if somebody does something wrong, I will say something about it.
"If they (the players) have an issue, then I don't mind anybody coming back to me and disagreeing."
