The Lions' bid for a hat-trick of flags is on shaky ground after three straight losses left them nursing a 6-6 record at the halfway point of the season.
And their hopes have been dealt another injury blow, with star midfielder Hugh McCluggage (calf) set for at least four weeks on the sidelines.
Brisbane were made to look second-rate in a 41-point loss to Geelong last month, then conceded a whopping 14 goals in the third quarter against GWS on the way to a 78-point defeat.
To rub more salt into the wound, last week's 25-point loss to Fremantle seemed like a symbolic passing of the baton as the Dockers showed why they are the new premiership favourites by surging to a 51-point lead in the third quarter.
Brisbane's task to get themselves back in the top-four race faces a major test on Saturday when they take on fifth-placed Gold Coast (7-4) at People First Stadium.
The Lions have won 13 of their past 15 games against the Suns - including a 53-point win in last year's semi-final - but Gold Coast are now a different beast with Christian Petracca running through the midfield.
"Obviously we've had a bit of a rough trot the last couple of weeks," Lions forward-turned-defender Ty Gallop said.
"But I think tomorrow getting us on the road again (will) get us up and about.
"The boys are up and about and the energy is good amongst the group.
"Obviously it (the Q-clash) is a high-stakes game - the only two (AFL) teams in Queensland.
"You know it's going to be on early, so just give it everything you've got."
McCluggage joins Keidean Coleman (hamstring) on the sidelines, with the Lions defender to spend at least five weeks out of action.
Experienced defender Darragh Joyce returns to the side, but the Lions are still without star veteran Dayne Zorko, who is battling a quad injury.
The Suns have handed a debut to Jai Murray, while Lachie Weller (hamstring) and Will Graham (concussion) have been cleared to return.
Former Bulldogs forward Jamarra Ugle-Hagan will make his return from an ankle injury via the VFL.
The Suns lost to North Melbourne by six points before their bye, and will be aiming to make amends in front of their home fans on Saturday.
