The Broncos sit in fourth place after the first game of the final round, but will be overtaken by North Queensland if the Cowboys beat the Titans on Saturday.
Canterbury is also an outside chance of passing last year's runners-up, but would need to beat South Sydney by 45 points on Friday to make that happen.
Regardless of how it ends up, Brisbane will happily take the two points for a fifth-straight week although the performance left a bit to be desired with the playoffs looming.
