Wayne Rooney faces a two-match ban by the Football Association (FA) for using offensive language during Manchester United’s 4-2 win at West Ham.
The United striker swore into a television camera after completing his hat-trick at Upton Park.
The England international has until 1800 BST on Tuesday to lodge an appeal against the FA charge.
If he accepts it, he will receive a two-match ban – if he denies the charge his hearing will be on Wednesday.
Rooney apologised immediately after the game for the incident.
The 25-year-old was in earning the three points for the Red Devils as he grabbed his three goals in 14 minutes to help his side come back from 2-0 down.
In a statement released by United on Saturday, the striker said: “I want to apologise for any offence that may have been caused by my goal celebration, especially any parents or children that were watching.
“Emotions were running high, and on reflection my heat-of-the-moment reaction was inappropriate. It was not aimed at anyone in particular.”
United team-mate Rio Ferdinand urged the media to show leniency towards Rooney via his Twitter account on Sunday.
The defender called for newspapers and radio “to give Wayne a break” adding “he knows what he did was wrong”.
Ferdinand said he had spoken to Rooney and the United forward was “genuinely sorry”.
FA rules state: “A participant shall at all times act in the best interests of the game and shall not act in any manner which is improper or brings the game into disrepute or use any one, or a combination of, violent conduct, serious foul play, threatening, abusive, indecent or insulting words or behaviour.”
