Walter Smith insists he has not dropped youngster John Fleck because of a row with his assistant Ally McCoist.
Fleck was a shock omission from the Gers' squad that contested the Emirates Cup over the weekend.
It led to reports that Fleck had been dropped from the first-team squad after a training ground bust-up with McCoist.
But Smith insists that Fleck was with the reserves because of "another reason".
"No, that is not the case," he said when asked whether Fleck was dropped because of his reported row with McCoist.
"I left him out for another reason and that's why he is off playing with the reserves in Northern Ireland .
"I made the decision to leave him out, I didn't even know about any incident."
In light of the bust-up, team-mate Nacho Novo has warned Fleck he needs to knuckle down.
"John Fleck is a great young player and he can do it for Rangers," said the
"He can do whatever he wants to do in the game with the ability he has. I
think he has the ability to become a very good player.
"The quality is there - now it is about how he is going to do it and what he
can do with his talent. I think for every player it is vital to work hard.
"A strong mentality and working every day is what you need to do.
"This is what all the senior players will tell John. He has all the talent but
you need to keep working hard."
