Jake Livermore will face no disciplinary action from the FA over his public confrontation with the West Ham supporter who taunted him about the death of his son.
West Brom and England midfielder Livermore has, however, been gently reminded by the game's disciplinary that he cannot take the law into his own hands.
He has been urged not to respond to provocation from the stands in future - not least for his personal safety.
Livermore became embroiled in a row with a spectator after being substituted in West Brom's 2-1 defeat at the London Stadium last week.
