Fiery Raiders forward Corey Horsburgh's brain snap against Parramatta's Ryan Matterson was sparked by a feud that stretches back some three years.
Horsburgh was sent to the sin bin for allegedly punching Matterson during a tough clash in Canberra, won ultimately 26-18 by the Raiders.
But the incident that saw him sent to cool his heels can be traced back to an infamous night at Bankwest Stadium in 2020.
