The referees body in England is investigating the incident that happened during Sunday’s 2-2 draw between the Reds and Arsenal at Anfield
Liverpool defender Andy Robertson has claimed that he was elbowed by linesman Constantine Hatzidakis at half-time of Liverpool's crunch match against Arsenal.
The Liverpool full-back was seen approaching the official, who then appeared to raise his arm towards the defender during the clash that ended 2-2 at Anfield.
Liverpool players surrounded referee Paul Tierney following the incident, with Robertson receiving a yellow card.
“I think the linesman throws an elbow,” said Jamie Carragher on Sky Sports commentary. Touchline reporter Geoff Shreeves confirmed Liverpool players had claimed Robertson had been elbowed by the official.
“Andy Robertson was absolutely apoplectic, stunned even,” Shreeves said.
Robertson said: "He's just elbowed me in the throat. The linesman has elbowed me in the throat".
Roy Keane and Gary Neville were asked whether they had seen anything like the incident. No, not really. Does he grab the linesman first? I'm not sure,” Keane said.
“Robertson's complaining, he should be more worried about his defending. I've watched him a number of times. He's a big baby. That's what that guy is. Just get on with the game, and concentrate on your defending.”
The PGMOL body, which governs referees in English football, has said it is investigating the incident.
