The Manchester United manager failed to fulfill media obligations in the aftermath of the Champions League defeat to Real Madrid after the Portuguese was controversially sent off
The Portuguese winger was sent off during the Champions League last-16 match after striking Los Blancos right back Alvaro Arbeloa with a high boot.
That decision left Ferguson, 71, infuriated and the Scot sent assistant Mike Phelan in his place to fulfil the club's media obligations after the game.
Phelan revealed that Ferguson was "too distraught" with referee Cuneyt's Cakir's performance to face the press in the immediate aftermath, despite his absence contravening UEFA rule.
The current Premier League leader could face further disciplinary action should defender Rio Ferdinand's sarcastic applause of Cakir shortly after the final whistle be mentioned in the official's report.
