Matt Giteau says there's an extra spring in the step of the Brumbies following their drought-breaking Super Rugby win over the Hurricanes.

Giteau said Saturday's 17-16 victory had lifted the side's eagerness at training on Monday.

The Brumbies had lost their previous five matches, of which four had been by seven points or fewer.

"It makes a difference," he said.

"The group is very enthusiastic getting back into training."

With their next match against the Western Force on Sunday, Giteau said the extra day would allow more time for the combinations of their three playmakers - Christian Lealiifano, Matt Toomua and himself - to gel.

A clash with James O'Connor was unlikely unless the Force star moved to five-eighth for the Canberra Stadium encounter, Giteau said.

"He played fullback on the weekend, so unless I get moved to fullback, I'm not too sure," he said.

O'Connor was moved to fullback for the Force's 31-3 loss to the NSW Waratahs last weekend, but Giteau said the young playmaker's influence on the Perth-based side could dictate a move closer to the ball.

"Whenever they go well, he's generally pretty heavily involved," he said.

Injuries continue to mar preparations for the Brumbies with Henry Speight ruled out for six weeks with an injured ankle.

Brumbies scrum coach Marco Caputo said winger Henry Speight was the only definite non-starter for this week following Saturday's match.

Adam Ashley-Cooper has recovered from a hip injury while hooker Huia Edmonds would have as much as time as possible for his injured hamstring, Caputo said.

Speight scored the sole try for the Brumbies on Saturday, but his absence adds to an injury toll including Wallabies captain Rocky Elsom (hamstring), Stephen Hoiles (achilles), Stephen Moore (ankle) and Mitchell Chapman (cheekbone).

Edmonds would be given every opportunity to recover before Sunday, especially with Moore unlikely to return for another fortnight, Caputo said.

"It is one that you need to treat cautiously because that sore point could quite easily degenerate into a tear if not managed well," Caputo said.

He said third-choice No.2 Anthony Hegarty would do most of the preparations for the match, while converted back-rower Elvis Levi has been called up as cover for hooker.

Giteau said the appointment of Steve Walsh as referee for Sunday's match posed no problems for him.

Last season Giteau was fined $5000 for disparaging comments about Walsh following the Brumbies' 19-12 loss to the NSW Waratahs.

"From my point of view, it is a clean slate," he said.
