Star recruit Matt Giteau has been included in a 23-man Brumbies squad ahead of Friday's Round 1 Super 14 clash against the Western Force in Perth.

Giteau, who remains a 50-50 chance of playing against his former Force team-mates as he continues to battle a quadriceps injury suffered in training a fortnight ago, has been named at fly-half.

Young gun Matt Toomua has been bracketed alongside the Australia number 10 and will partner Christian Lealiifano in the midfield if Giteau is unable to prove his fitness.

Brumbies coach Andy Friend admits the Wallabies ace is no certainty to take the field in the season opener, but confirmed the 27-year-old will be given until game day to prove his fitness.

"Matt's still touch and go at this stage," Friend said.

"You never want to leave a player like that out of the side and we'll be giving him every opportunity to play against his old side.

"He's comfortable with where he's at at the moment and the medical staff has been pleased with how it's been progressing.

"We'll be giving him up until the last possible minute on Friday but we're very mindful that you don't want to be risking someone like that should they not be 100% ready to go."

The Brumbies' other new face Rocky Elsom is expected to play after overcoming a hamstring complaint that prevented him playing a trial match with his new club.
