With two very specific exceptions (cf. Law 14 and Law 15), a free kick (or penalty kick) cannot be awarded for an offence committed with the ball out of play. Therefore, despite any misbehaviour by either team after a goal is scored, the correct restart is always a kick-off.
Law 12 - Fouls and Misconduct, Introduction:
Direct and indirect free kicks and penalty kicks can only be awarded for offences committed when the ball is in play.
Law 12 - Fouls and Misconduct, Section 4 - Restart of Play After Fouls and Misconduct:
- If the ball is out of play, play is restarted according to the previous decision
However, this does not prevent a referee from taking disciplinary action.
Law 12 - Fouls and Misconduct, Section 3 - Disciplinary Action:
A player is cautioned if guilty of:
Cautions for Unsporting Behaviour
There are different circumstances when a player must be cautioned for unsporting behaviour including if a player:
- commits in a reckless manner a direct free kick offence
- shows a lack of respect for the game
Celebration of a Goal
A player must be cautioned for:
- gesturing or acting in a provocative, derisory or inflammatory way
A player, substitute or substituted player who commits any of the following offences is sent off:
- biting or spitting at someone
- violent conduct
- using offensive, insulting or abusive language and/or gestures
The referee has many grounds on which to sanction players (from either team) for inappropriate behaviour after a goal has been scored. In addition to the above, the referee may also choose to have a quiet word with or publicly warn any players involved, if they felt that this was more appropriate than a formal sanction as listed above.
