The Rugby Football League will investigate the incident following yesterday’s Super League clash between Salford and Leeds at the AJ Bell Stadium.
Referee James Child was struck by a plastic cup at full-time as he made his way down the tunnel, with the home supporters venting their anger towards the official.
The Red Devils, who lost the match 50-24, released a statement yesterday evening condemning this behaviour with a lifetime ban to be imposed on the culprit.
In a short statement of their own, the RFL said: “The Rugby Football League is aware of an incident involving a supporter at the end of the Salford Red Devils and Leeds Rhinos fixture at the AJ Bell Stadium yesterday (Sunday, July 9).
“Physical and verbal abuse towards a match official, player, coach or fellow spectator is absolutely unacceptable and will not be tolerated by the Rugby Football League.
“Rugby League grounds are a place where everyone should be able to enjoy watching and participating in our sport and this enjoyment should not be ruined by the actions of a small number of individuals.
“The Rugby Football League is reviewing the incident that took place on Sunday and will provide an update when complete.”
