Brumbies fullback Mark Gerrard is confident he'll be fit to face Queensland, but says his presence won't cure all the ills of the Wellington hiding his teammates suffered last week.

The Brumbies' Super 14 semi-final hopes were dealt a massive blow by the 56-7 thrashing against the Hurricanes, a match Gerrard missed with the hamstring injury that also forced him to miss the victory over the Bulls.

But while the former Wallaby said he was ready to bring his booming kicking game to Suncorp Stadium on Saturday, he warned the Brumbies needed to tighten up their defence for him to be effective.

"We don't really want to rely on my kicking, I just happen to have a kicking game," he said.

"Kicking's a by-product of good defence.

"We defend well, I can turn a team around no problem in the world, (but if) we don't defend well and we don't sweep well - I don't think we can play the football that we want to play."

Gerrard felt he could have played and was disappointed to miss the Wellington match.

But the 26-year-old said the Brumbies could bounce back against the Reds, who are coming off a surprise win in Auckland against the Blues.

"There was a few blokes that reckon I wasn't (fit), I felt that I could've (played)," he said.

"History says my hammies aren't that good anyway so I'm better off missing an 80 minute game of football than probably having to sacrifice the next four weeks.

"I'm just there to contribute what I can to the side, if it's to be turning a team around and pin them back down in a corner then I'm quite happy to do that all day.

"I'll use it (kick) as often as I can and probably try to get us in the right positions.

"Hopefully in doing that I can put us in good field positions to play some good football and hopefully score some good points against the Reds."

Gerrard's return as well as the expected return of Gene Fairbanks will give Brumbies coach Andy Friend plenty to ponder as he reshuffles his backline for the Reds.

But Friend said youngster Matt Toomua will keep hold of the No.10 jersey he wore against the Hurricanes for his Super 14 starting debut.

"I think Matt showed us that he can play 10," he said.

"Gene playing outside him at 12 gives us good direction as well and with Tyrone (Smith), who I think has had a great year, I think he's probably been one of our best on the field, so I think those two fellas in the midfield are pretty handy."

That shuffle would put Wallabies captain Stirling Mortlock and fellow international Adam Ashley-Cooper on the wings against the Reds with Alfi Mafi and Francis Fainifo making way.
