On 10 May, Sims groped the genitals of opposition player and former team mate Willie Mason, an action described by Rugby League writer Brad Walter as being "infantile", "bizarre and offensive", and worthy of punishment due to the potential for the incident to portray the NRL in a distasteful and damaging light.
Despite some rugby league reporters calling for harsh disciplinary action as a result of the incident, Mason was unperturbed, stating that he found the incident "hilarious." Sims received a warning from the NRL match review committee.
Sims apologized for any offence caused to those who were watching the game and described it as a "harmless gesture between two friends."
