The Broncos face challenges with their Sunday preliminary final matchup for the NRL grand final.
The Broncos face being disadvantaged if they reach this year's NRL grand final after their home preliminary final was locked in for a Sunday afternoon at Suncorp Stadium.
Brisbane's grand final qualifier against the Bulldogs or Penrith has been slated for September 28 in a rare Sunday fixture for the Broncos at Suncorp.
Meanwhile, the Storm's preliminary final against Canberra or Cronulla will be played on Friday night, September 26, to avoid a clash with the AFL grand final in Melbourne on Saturday afternoon.
The NRL has taken the unprecedented step of scheduling this year's preliminary finals two days apart in a bid to capitalise on the brilliant success of the Broncos-Raiders finals epic on Sunday.
