Ferguson was silent after Sunday's loss to Liverpool |
Sir Alex Ferguson refused to speak to media rights holders following the game at Liverpool on Sunday which Manchester United lost 3-1.
The United manager did not speak to host broadcaster Sky Sports, radio rights holders TalkSport and the club's television channel MUTV.
His assistant Mike Phelan did not carry out his usual post-match engagements with the BBC.
The decision not to talk to the media was made before the game.
Should any of the media organisations complain to the Premier League, the governing body would be forced to act.
Ferguson has not given a post-match interview to the BBC since 2004 after a BBC Three documentary about his son Jason, who was then working as a football agent.
The Premier League was due to discuss Ferguson's BBC boycott, which is in contravention of its rules, late last year, but if any fines were imposed for his non-compliance they have yet to be made public.
However, it is believed no media organisation has ever lodged an official complaint over the issue.
Ferguson cancelled his pre-game briefing on Friday in protest at the coverage given to his post-match quotes at Chelsea on Tuesday for which the Football Association charged him with improper conduct .
His action was also prompted by the furore that surrounded Wayne Rooney's elbowing of Wigan's James McCarthy last weekend.
Ferguson said he had "feared the worst" when referee Martin Atkinson was appointed for the game at Stamford Bridge with Chelsea, which United lost 2-1 after leading at half-time.
He denies the charge and will have a personal hearing at a date no later than 25 March.
The Scot also has two matches of a four-game ban from last season hanging over him after remarks about referee Alan Wiley.
It is not yet known whether the media blackout will continue this week, ahead of United's FA Cup quarter-final with Arsenal, although discussions are bound to take place behind the scenes.
However defender Rio Ferdinand, who was not at Anfield as he recovers from a calf injury, offered his opinion via Twitter.
"Bad result today, no excuses," he said.
