The Manly Sea Eagles looked to have scored a late try to give them some hope.
But it was ruled no try because of a knock on from Brayden Wiliame in the lead up.
Kieran Foran had run to the left and passed wide to Wiliame. The centre dropped the ball but it went wide straight to Cheyse Blair, who broke through the line.
Blair then found Wiliame on the inside to score what would have been his second try of the night. The referee went upstairs though and said no try because of the knock on.
It was a tough one for the Sea Eagles as they needed the score to have any hope of reeling the Dragons in. With just six minutes on the clock the home team is 12-4 in front.
