Chelsea striker Nicolas Jackson clashed with Everton players at the end of yesterday's 2-0 defeat.
At fulltime, Jackson was seen confronting several celebrating Everton players, including Amadou Onana and Nathan Patterson.
Nizaar Kinsella of the Evening Standard reported: "Nicolas Jackson had to be pulled away from some kind of confrontation after the match.
"(Mauricio) Pochettino pulling him away and then one of his assistants dragging him down the tunnel, protecting him from a red card."
It's suggested Onana pushed Jackson before the Chelsea striker was dragged away by teammates and Pochettino.
