John Brown has been issued with a notice of complaint by the Scottish Football Association for comments he made in a media interview.

The Dundee manager has been offered a one-match suspension after being charged with "making comments in a media interview that criticise a decision and the performance of the match officials in such a way as to indicate incompetence".

Brown was unhappy with decisions made by referee Alan Muir during Sunday's 1-1 draw against Aberdeen, with the result confirming his side's relegation from the Clydesdale Bank Premier League. Dundee needed a win to keep alive their slim hopes of avoiding the drop but were held to a draw when Peter Pawlett went down in the box to win a controversial penalty, which was converted by Niall McGinn to cancel out Jim McAlister's opener.

Brown accused Pawlett of diving and also felt his own side had a spot-kick appeal of their own wrongly turned down. Speaking after the game, he said: "You expect officials to do their job and it makes a mockery of it. I haven't really criticised the player [Pawlett] yet but to take a dive, he should be ashamed of himself. But, there you go. How many cheats are there in the game?"

He added: "[We have] a referee that can go to his work on a Monday morning and can sleep well tonight. This is our livelihoods. It has been taken out of our hands. It is a shocking decision for the penalty kick. That has taken us down. That decision has taken us down and it's a disgrace. It is the worst thing I have ever seen. He can't get it right."

Brown's own notice of complaint came on the same day that Pawlett accepted a two-match ban for "causing a match official to make an incorrect decision by committing an act of simulation" after the club confirmed they would not be pursuing an appeal.

An Aberdeen spokesperson said: "The action the club has taken does in no way mean we are not backing our player. While there was undoubtedly contact in the incident, we feel we would rather draw a line under the situation. The trial by television and subsequent coverage in sections of the media had almost sealed Peter's fate and as a result it was felt an appeal would have been fruitless."
