Brisbane have bounced back to winning ways with a convincing 32-6 victory over St George Illawarra on Friday night.
The Broncos will hold on to the NRL top spot for at least another week after the six-tries-to-one win, which ends a two-game losing run.
The Dragons, with Benji Marshall unavailable due to a hamstring strain, threw up a surprise when coach Paul McGregor named forward Jack De Belin at halfback.
The gamble didn't pay dividends however with the Dragons dominating territory in the first half but coming off the field 16-0 behind at the break.
The Broncos, who only had 11 tackles inside the Dragons' 20 in the first half, made the most of every trip through tries to Jordan Kahu, Lachlan Maranta and Anthony Milford.
