Constantine Hatzidakis, who appeared to elbow Andy Robertson in the jaw in April 2023, has been given his first Liverpool match since the controversial incident.
The official was suspended while his encounter with the Reds defender was investigated by chiefs.
However, the he was cleared of any wrongdoing by the Football Association after television footage appeared to show him apparently elbow the player at half-time of a 2-2 draw with Arsenal at Anfield.
Hatzidakis was understood to have apologised to Robertson on a Zoom call, with the Scotland captain accepting his explanation for what happened, and the FA choosing to take no further action.
Manchester United's clash with Aston Villa two weeks later marked Hatzidakis's return to the pitch for a Premier League fixture. He had officiated a Championship fixture between Preston North End and Blackburn Rovers shortly before.
In the 21 months that followed, the Englishman's encounters with Liverpool were limited to three matches in the VAR seat, but now he is set to meet Robertson once again in his first on-field Reds game since the incident.
Arne Slot's men face Tottenham Hotspur in the first leg of the Carabao Cup semi-final on January 8 and Hatzidakis will be running the line on that night.
James Mainwaring will join the official as an assistant referee, while Stuart Attwell is set to be the referee for the cup tie. Tim Robinson will be the fourth official.
Robertson claimed Hatzidakis elbowed him in the face after he approached the official as he walked off during Liverpool's Premier league match against Arsenal at Anfield earlier this month.
The clash was caught on camera – with Robertson and his team mates protesting furiously to the match referee over the incident. However, the FA conducted an investigation of their own, drawing the conclusion that no further action was required.
'We have thoroughly reviewed all of the evidence in relation to the recent incident at Anfield involving the Liverpool defender and match official, and we will be taking no further action,' read an FA statement.
'Our comprehensive process involved reviewing detailed statements from Liverpool and PGMOL, as well as multiple angles of video footage, in relation to both the incident and its surrounding circumstances.'
Meanwhile, Hatzidakis released a statement after his conversation with Robertson, stating his excitement at the prospect of returning to action, as well as highlighting that it was not his 'intention' to make contact with the player.
'I have discussed the matter directly with Andy Robertson during an open and positive conversation,' his statement read.
'It was not my intention to make any contact with Andy as I pulled my arm away from him and for that I have apologised.'
The return of Hatzidakis is unlikely to faze Slot, who has unflappably led Liverpool to a six-point lead at the top of the Premier League with a game in hand.
The Reds also find themselves at the summit of the Champions League and in the semi-finals of the Carabao Cup, having lost just one match all season.
Slot arrived at Anfield in the summer and was not in the dugout for the incident in April 2023. Jurgen Klopp was Reds boss that day but announced his departure nine months later.
