Liverpool defender Jamie Carragher will not face an FA misconduct charge after throwing a coin back at Arsenal fans.
But the 24-year-old defender will receive a formal police warning for the incident at Highbury on Sunday.
The two people who allegedly received injuries have declined to make allegations.
Red card
After he threw back the coin, Carragher was immediately dismissed from the FA Cup match for violent conduct.
The red card means Carragher will miss England's friendly against the Netherlands on 10 February.
He's banned for three matches and fined £40,000.
