Wayne Bennett has declared the Hamiso Tabuai-Fidow centre experiment over as the Dolphins' NRL finals hopes go on the line against a re-stocked Canterbury.
Fresh off a bye, the Redcliffe side will face the Bulldogs at Bundaberg's Salter Oval on Sunday.
The competition newcomers are four points - or two wins - outside the top eight with six rounds remaining.
Bennett has shuffled his deck, returning the Queensland Maroons' centre to fullback, where the coach believes he's at his best and where he started the season in hot form.
"We've finished with the centre experiment ... moving on and he's our fullback," Bennett said on Saturday of Tabuai-Fidow's two-week stint in the centres.
It means Kodi Nikorima will move from fullback to the No.6, Valynce Te Whare will play centre and playmaker Anthony Milford will have a floating role on the bench.
Hooker Jeremy Marshall-King is named to return after nursing an ongoing shoulder injury in a boost Bennett is not underestimating.
"We've missed him a lot; has been one of our top three players this season, in that category," Bennett said.
"It's been a mixed few months for him, but he's pretty confident now and feels he's over his shoulder problems."
The Bulldogs are 16th with a 6-13 record and welcome back Viliame Kikau (pectoral) for his first game since the fourth round.
Toby Sexton and Jacob Preston are also back for the Bulldogs.
"They've obviously missed him and he'll have a big impact on the game," Bennett said of backrower Kikau.
"But it depends how we defend him that will determine what sort of impact he does have.
"He's a wonderful player and good to see him back."
Bennett wouldn't be drawn on the importance of this game, or how he rated the team's maiden NRL campaign.
"I haven't thought about a pass mark since the first day I came here," the coach said.
"I'm not really interested in pass marks. We'll see where we're at (once the season ends), but I don't even think I'll have a review about it.
"Just move to next season; we're doing our best most weeks, there's only been two or three games that I've been disappointed in them, otherwise they've been a pretty good football team."
