The Football Association and Everton are set to investigate an incident in which striker Richarlison threw a torch into a crowd while celebrating his goal against Chelsea on Sunday night.
The Toffees beat Chelsea 1-0 to boost their chances of survival in the Premier League after the Brazilian capitalized on a mistake by Cesar Azpilicueta to claim the win.
Although his celebrations caught the attention of the club and the Football Association, after he chose a lit torch and threw it into the crowd at Goodison Park.
With fireworks banned in English football stadiums, the accident could cause the Brazilian to fall into hot water.
The victory over the European champions, who had yet to win on the court in the past five years, put them up to 32 points, and they could get out of the red zone if they win their match in hand.
On the other hand, Chelsea entered the top four race, after winning both Arsenal in fourth place and Tottenham in fifth.
With four matches remaining, the battle at both ends of the table will end to the bottom.
