Speaking at Lennoxtown ahead of Sunday's SPL clash with St Johnstone at McDiarmid Park on Sunday, Mowbray reiterated his stance on the matter.
He said: "Do I talk to my players? Every day. It's my job is to talk to footballers.
"Was there a meeting at Christmas-time telling him (Brown) he could go? Never.
"He didn't misunderstand me.
"It was a total mis-truth and I think the club and myself have made that pretty clear.
"It's not disruptive because it's not true."
