... one of the worst in Premier League history!
But ... and there is a big "but" ... he believes if Sunderland receive an apology from the referees' body, manager Gus Poyet should not make it public.
Dermot Gallagher: "It was a total surprise when the red card came out... I would be very surprised if Sunderland are not successful with their appeal.
"It was an error.
"Brown made a low, one-footed tackle, he won the ball, didn't take anyone out with his trailing leg, the ball went on and nobody on the pitch really thought it was a foul.
"It was a total surprise when the red card came out. But it was something like the 1266th red card since the start of the Premier League and it was inevitable there would be one like that.
"Let's hope it's another 21 years before we are talking about another one. I would be very surprised if Sunderland are not successful with their appeal.
"I am mystified by this apology business.
"Right from when referees turned professional in 2001, there has been regular dialogue between the managers and the guys in charge of the PGMO.
"Performances are talked through, managers can express their views and they talk it over because we don't always see it the same way. It is a two-way thing.
"The disappointing thing is this has been going for years but this is the first time I can remember somebody has come out and talked about one of the conversations.
"It is not about ringing and apologising, but being on the end of a phone if a manager wants to go through different situations."
