The North have won all three games to date whilst the Dragons find themselves rooted to the foot of the table after three successive defeats.
Craig Atwell's try and 14 points from the boot of Joseph Evans gave the Dragons a chance of victory in their last game, against the Scarlets at Narberth, but their hosts rallied in the final quarter and secured a 24-19 victory.
Meanwhile, the Ospreys U20 will take on the Scarlets at Narberth tonight in a game that was postponed, due to a waterlogged ground on October 25th.
