If confidence is any guide, rookie ACT Brumbies flyhalf Matt Toomua will have no problem replacing Christian Lealiifano at pivot in Wellington on Saturday, should coach Andy Friend opt for him.

Toomua and Gene Fairbanks are vying for the vacant Brumbies' No.10 jersey for the round 11 Super 14 match against the Hurricanes on Anzac Day.

Friend remained unsure yesterday who he would name at flyhalf to cover for Lealiifano, who is sidelined with a hamstring injury.

The crucial selection will largely depend on the fitness of winger Alfi Mafi.

Should Mafi fail to recover from a groin injury that kept him out of last weekend's 32-31 win over the Pretoria Bulls, Toomua would likely be named at flyhalf with Fairbanks at inside centre, Tyrone Smith at outside centre and Stirling Mortlock on a wing.

But if Mafi is cleared to play, he would join Francis Fainifo on the wings, meaning Mortlock could move to 13, Smith to 12 and Fairbanks to 10.

Toomua accepted his possible selection was dependant on another player's fitness but backed himself to succeed if he got the call-up from his coach.

"If I'm picked, I'm ready, I know I am, I'll be confident out there," he said.

"I've had a few runs at 10 during the games [this season] and obviously at training we're filling in all the time so it will be a simple transition for me.

"You want to be starting, you want to be playing 10, so I'm not going to hide that.

"I want to be picked but if I'm not, Friendy is doing what is best for the team and I back him."

Fairbanks, too, is ready to wear the No.10 jersey for the first time this season should Friend ask him to.

The 26-year-old is a specialist inside centre but spent time playing at flyhalf earlier in his career.

He admitted he preferred the role of inside centre but wouldn't hesitate to move in to pivot if required.

"I'd be happy to do it and I'd be confident with Matty at 10 as well," Fairbanks said.
