Days before a crucial board meeting that will shape Griffin's future at the club, the Dragons took a 4-0 lead to halftime but were unable to stop the Raiders in the second half.
It was far from pretty from the Raiders but a crucial victory nonetheless, winning consecutive games for the first time this season and moving to 3-4 to keep touch with the pack in the race for the top eight.
The Dragons' fourth loss in five outings couldn't have come at a worse time for Griffin, immediate results looking crucial with his future likely to be decided in the next month.
