Brumbies utility back Matt Toomua is set return to action in Saturday's clash with the Crusaders in Canberra.
Toomua started the season as the Brumbies' first-choice fly-half but was sidelined for four weeks due to an ankle injury.
He returned to action at inside centre against the Lions in Johannesburg in Round 14 but aggravated the injury and hasn't played again.
According to scrum-half Nic White, Brumbies boss Stephen Larkham is set to continue with Christian Lealiifano at fly-half if Toomua returns to action this weekend.
But there is still uncertainty over the fitness of right wing Henry Speight who also injured his ankle in last weekend's win over the Western Force in Perth.
"He'll probably go the same as the Lions [game] – leave [Lealiifano] at 10 and [Toomua] at 12, but they interchange so well," White told the Canberra Times.
"[Speight] did some change of direction and I assume he'll have right up until Saturday to prove his fitness.
"We've got good depth, but both of those guys are world class and having them is a huge boost."
The Brumbies are assured of a spot in the Finals Series but can finish second in the table – and win the Australian Conference – if they beat the Crusaders and the Waratahs fail to beat the Reds in Sydney.
