The PGMOL have confirmed they will review the incident in which Liverpool defender Andrew Robertson appeared to be elbowed by linesman Constantine Hatzidakis at half-time 'in full'.
The clash occurred at half-time of the Premier League visit of Arsenal to Anfield on Easter Sunday. Arsenal led 2-1 after goals from Gabriel Martinelli and Gabriel Jesus.
Robertson approached the official, who then appeared to raise his arm towards the defender. Liverpool players surrounded referee Paul Tierney following the clash, with Robertson receiving a yellow card.
