Everton forward Richarlison has been charged by the FA for throwing a flare into the crowd after scoring the winner in his side's vital 1-0 victory over Chelsea last month.
The Brazilian seemingly got caught up in the celebrations following his 46th-minute goal, which proved crucial in the Toffees avoiding the ignominy of relegation.
Richarlison sparked fury by hurling the lit missile, which had been thrown onto the pitch by the crowd, back into the stands at Goodison Park.
Everton are also investigating the incident but hinted they did not feel the 25-year-old was guilty of deliberate wrongdoing.
The flare was visibly lit and burning, so posed a substantial health hazard for the supporters packed into the stand.
Richarlison was slammed for his conduct on social media. 'Richarlison really is f***ing thick,' one fan said on Twitter.
In a similar incident in February, Liverpool starlet Harvey Elliott was contacted by the FA after holding a red flare at Wembley after his side won the Carabao Cup.
