Refereeing body PGMOL will investigate after Liverpool’s Andy Robertson appeared to be elbowed in the chin by assistant referee Constantine Hatzidakis.
Robertson approached the official angrily at the end of the first half against Arsenal and appeared to shove him as he passed, with Hatzidakis raising an elbow which hit Robertson.
The Scot reacted furiously and, along with several team-mates, approached referee Paul Tierney, who booked 29-year-old Robertson.
Sky Sports pundit Roy Keane called the Reds player a “big baby” for his reaction.
“Robertson should be more worried about his defending,” said Keane. “Just get on with the game. He grabs the linesman first.”
Robertson could be in big trouble if the incident is investigated further. Fulham’s Aleksandar Mitrovic is currently serving an eight-game ban for pushing referee Chris Kavanagh in their FA Cup loss at Manchester United on 19 March.
PGMOL’s statement said they were “aware of an incident involving assistant referee Constantine Hatzidakis and Liverpool defender Andrew Robertson at half-time during the Liverpool v Arsenal fixture at Anfield.”
It added: “We will review the matter in full once the game has concluded.”
