The FA has written to Harvey Elliott following the Liverpool star's handling of a flare after the Carabao Cup final.
Chelsea lost in a dramatic penalty shootout, with Elliott slotting home with maturity beyond his years, and the 18-year-old became the club's youngest player when they won their first piece of silverware at Wembley.
His joy at full-time was clear as he savored the festivities, but English football's regulatory body has raised concerns with the teenager plainly spotted carrying a red flare during the celebrations.
Elliot came off the bench in the 79th minute, replacing Jordan Henderson as Liverpool sought a winner.
The player has been contacted directly, while the has club declined to comment on the situation when approached.
