Fulham chiefs fear manager Marco Silva will be hit with an extended ban by the FA after his dismissal at Manchester United.
Silva was charged for his red card and also hinting at bias from ref Chris Kavanagh in post-match comments.
He is now heading for his second touchline ban of the season - but has already apologised for the remarks.
Fulham accept their manager must be punished.
But there are fears Silva will be made an example of as manager behaviour becomes a growing issue in the game, says The Sun.
The FA appealed a fine for Liverpool boss Jurgen Klopp earlier this season which eventually saw the German banned for a game after abusing a fourth official.
