Raiders firebrand Corey Horsburgh has been sin binned for punching Eels' Ryan Matterson in the first half of the Canberra-Parramatta clash.
The incident came about soon after Andrew Davey knocked the ball on close to the line and the Raiders attempted to play on.
Matterson ran in to try and stop the Raiders escaping the in-goal which Horsburgh took issue with and threw a punch which caused players to join from everywhere.
