Scans on the injured hamstring of Brumbies scrum-half Josh Valentine are expected to reveal it is not as serious as first thought.

Valentine came from the field early in the first half of the Brumbies 30-23 win over the Chiefs with a hamstring injury on Saturday.

A spokesman for the ACT club said they were still awaiting the results of scans late on Monday afternoon but were confident there was no tear or serious injury and the 27-year-old would be available against the Cheetahs in two weeks.

However coach Andy Friend said the hamstring may have been the least of Valentine's worries after a visit to the dentist.

"He's getting his wisdom teeth out today so he's got a few more issues to deal with there," Friend said on Monday.

With the Brumbies already dealing with a string of injuries, Friend is praying Valentine gets the all clear.

Friend said he still had received no indication on how long veteran flanker George Smith will remain on the sidelines after injuring his shoulder two weeks ago against the Blues.

"There's still no response from that nerve in the shoulder and they need to normally give it about three weeks (rest) and then look for some other treatment," he said.

"We had lengthy discussions about that this morning and we're no clearer on what the future holds for him."

The Brumbies have a bye this weekend - and it couldn't have come sooner.

"We've got a lot of boys who are carrying little niggles and halfway through the season it is a pretty good time for it," Friend said.

"We'll use the week well and give them a bit of refresh and then hopefully finish off the back half of the season in better form."

The Brumbies are in fifth spot after five wins from their opening seven games.
