With the Warriors well beaten in the latter stages, Hock appeared to gouge the eyes of Warrington forward Ben Harrison in the tackle. When Harrison got to his feet, a punch was thrown by the Wigan man, sparking a minor skirmish between players from both sides.
The incident, clearly caught on the SKY TV cameras, has led to fans on social networks calling for a ban for the 27-year-old. If found guilty, the RFL recommend a minimum four game ban as per their disciplinary guidelines, meaning Hock would miss the rest of the season.
Hock returned to action this season after serving a two-year ban for using an illegal substance.
