Three years on since Raiders forward Corey Horsburgh flipped off fans, the enforcer's rivalry with Ryan Matterson has continued after he punched the Eels lock on Saturday night.
Tensions erupted at GIO Stadium when a melee broke out after a knock on from Eels second-rower Andrew Davey.
Horsburgh then ran in and set his sights on Matterson, throwing a punch at the Eels forward before a number of players attempted to break it up.
