Wayne Rooney is appealing against his two-match ban for swearing into a TV camera during Manchester United's match against West Ham.
The Football Association punished him for his rude celebration of his hat-trick on Saturday.
The striker admitted he used bad language but says he shouldn't be banned for two matches.
Football bosses will look into whether the ban's too much at a special meeting on Wednesday.
The striker quickly said sorry after United's 4-2 win at Upton Park when he swore down a pitch-side television camera.
If the two-match ban goes ahead, Rooney will miss this weekend's match against Fulham and then the FA Cup semi-final against Manchester City.
But if the FA thinks he doesn't have any sensible grounds for appeal then he faces the risk of having his ban increased to three matches!
This would also rule him out of the league game at Newcastle United.
Manchester United currently top the Premier League by seven points, although second-placed Arsenal have a game in hand.
