Brown had the bust-up on the pre-season tour of America and has
not started a league game since.
And he believes his Old Trafford stay is now in doubt.
The argument was over a night out organised by United's players.
Brown is understood to have been told by boss Fergie he could not
go - although it is not clear why - leading to the row.
The defender, 31 this Wednesday, stood his ground and Ferguson
was described as 'incandescent' as they traded verbal blows.
Since then, Brown has had to make do with a start against
Rangers in the Champions League - when Rafael cried off late
through illness.
And he began the Carling Cup third-round tie with
Scunthorpe.
Brown, who joined United as a pro in 1996, did not get off the
bench in the Premier League win over Liverpool last month.
He made the Euro trip to Valencia but was left out of the squad
on the night.
The former England star, who won 23 caps, has made 349
appearances for the Old Trafford giants.
He is one short of 200 Premier League starts but may not get the
chance to reach that milestone with his current club.
Brown fears being sold in January - with Sunderland keeping an
eye on developments.
The versatile defender, who has 1½ years left on his deal, was
diplomatic when asked last week whether he is frustrated on the
sidelines.
He said: "Yeah, a little bit. But I've always had to deal with
that situation throughout my career.
"It's something I've learned to handle. We've got lots of good
players in defensive positions.
"I have to keep training hard and, when I do get a chance, play
well.
"There's no point sulking and letting it get to you.
"It might be difficult but you have to remember that everyone
wants to play every week. Unfortunately, that can't
happen."
