Wayne Rooney can expect to discover on Monday whether he will face disciplinary action for his foul-mouthed hat-trick celebration.
The Manchester United forward's three goals helped his team to a 4-2 victory at West Ham which took them seven points clear at the top of the Barclays Premier League.
But, after completing his treble, the striker uttered an audible expletive into a television camera as he celebrated and the Football Association's director Sir Trevor Brooking has confirmed the governing body will be investigating Rooney's behaviour at Upton Park.
"[On Monday] there will be a decision," he told BBC Radio 5 Live's Sportsweek programme. "It was a surprise, after scoring a hat-trick, to react that way. It is something we will have to look at."
Rooney has already apologised for swearing. His outburst, beamed around the world by Sky Sports, prompted an on-air apology from the broadcasters.
In a statement released by United, Rooney 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."
