The assistant referee involved in an incident with Liverpool's Andy Robertson has been punished "enough", says the head of a referees' charity.
Constantine Hatzidakis has been stood down while an investigation into the incident on Sunday, in which he seemed to elbow Robertson, is completed.
Former Premier League referee Keith Hackett said Hatzidakis' career "could be in jeopardy" if found guilty.
"It has been blown a little bit out of proportion," said Martin Cassidy.
Cassidy, the chief executive officer of Ref Support UK, added: "We should never advocate violence or match officials hitting anyone but it genuinely looks like Andy Robertson grabs him and Con pushes him to get off.
