The desperate Brisbane Broncos believe they will receive no second chances if rolled in Saturday night's NRL finals derby on the Gold Coast.

Broncos pack leader Corey Parker on Wednesday underlined the importance of a rare away victory at Skilled Park by rating it a "do-or-die" elimination match.

Parker expects to see at least one finals upset, leaving Brisbane terribly vulnerable, due to the form of seventh-placed Newcastle and eighth-placed Parramatta.

If either the Eels down minor premiers St George Illawarra or the Knights beat the second-placed Bulldogs, then the Broncos' season would end if they lose to the third-placed Titans.

"It's do or die for us and that's how we're going to treat it," Parker said.

"To the players and the club it means everything.

"The way the comp is at the moment and the way the lower teams have performed in the last three or four weeks anything is possible.

"Certainly that's in our mind and we don't want to be sitting over the weekend and waiting on results."

A loss at Skilled Stadium will see the Broncos hope and pray the Bulldogs win on Saturday night and the Dragons back-up to beat the Eels for a second time in 10 days.

Brisbane are favourites for the south-east Queensland derby, their first finals clash. Bookmakers have listed the Coast at $2.60, but Parker disputes that price.

"I don't know who writes the odds but they're a side who finished third and rightly so," the in-form lock said.

"They played consistently well all year so for us to be favourites it's surprised us.

"They've only lost one at home (this season).

"They obviously take a bit of pride in their own back yard but in saying that it's a new competition at semi-final time."

The Broncos are preparing as though Titans dual international Mat Rogers will play despite a hamstring injury sustained in their 38-4 last-round thumping by Manly.

"It's a semi-final. Everyone wants to play semis so we expect him to play," Parker said.

Prop Nick Kenny (ankle) trained at Red Hill on Wednesday in a sign he'll be fit to start against the Titans.

Former Queensland forward Parker, a two-try star in the 22-10 win over Canberra, has enjoyed his most consistent season in the NRL.

He has made the most of extra responsibility in the Broncos leadership group, as well as more latitude in attack by taking Tonie Carroll's place at lock.

"Throughout the year I've been given that free rein role at lock forward," he said.

"It's a change for me but one I've been enjoying.

"This season I set myself the goal to use some maturity and lead from the front. Hopefully I've done that."
