"We've got some big boys back," said Liam Messam, another returning from a minor injury.
"It's good to have Brodie back. He's probably worth about 300kg a game. He's played bugger-all for us this year and I know he's chomping at the bit to get out there."
Retallick confirmed as much, describing his stop-start season as frustrating but finding the bright side in what is the most important year of the 24-year-old's career.
"It's probably the first time in four years that the body and mind have felt this good so long into a Super season," he said. "But I'm just looking forward to getting out on to the park and hoping I have that energy and bring some impact.
"It's a pretty important game in terms of how our season's going to finish up so it's a great time to be back out there."
Retallick admitted there would be a bit of rust and maybe even a touch of nerves at Suncorp Stadium, understandable after both shoulder joints betrayed him at different times this year. Neither injury was especially serious - the second could have gone undetected if not for a precautionary scan - but both required relatively lengthy recovery periods.
They combined to leave Retallick short of game time and leave the Chiefs without one of their most important players, part of a locking crisis that at one stage saw a pair of loose forwards occupy the second row.
The tide seems to have finally turned for Dave Rennie's side, with Matt Symons also returning to the bench after battling concussion.
"We're really rapt to have Matt and Brodie back," the coach said.
"It certainly gives us a fair bit of steel and a lot of experience.
"You noticed [Retallick] in training - he was pretty fired up and pretty keen to go. It's good to have him back, along with a couple of others. We needed that."
Tom Marshall is another to shake off injury and take his place at fullback while Rennie was "really confident" of Sonny Bill Williams being passed fit to tackle the Hurricanes next weekend.
