Jonjo Shelvey has been "reminded of his responsibilities" by the Football Association after the Swansea midfielder made provocative gestures during the all-Welsh Premier League derby against Cardiff.
The FA investigated the incident where Shelvey made swimming gestures - an apparent reference to an alleged 1988 incident in which Cardiff fans went into the sea as supporters clashed.
An FA spokesman said: "Following an investigation, the FA has reminded Jonjo Shelvey of his responsibilities. No further action will follow."
