Flyhalf Stephen Larkham is expected to be out of the Brumbies' line-up for three weeks after being cleared of a fracture in his upper chest.

The gifted playmaker suffered a subluxed sternoclavicular joint during the Brumbies' 11-10 Super 14 loss to the Hurricanes in Wellington on Friday night.

He underwent a CT scan on Monday morning that cleared him of any fractures in the joint and hopes to be available to take on the Sharks in Durban on March 24.

"I got tackled by Tana (Umaga), my shoulder was down and it got jammed," he said in a team statement.

"It wasn't particularly painful (at the time) but I knew that something was wrong straight away.

"I'm relieved that the injury's not as serious as it could be.

"The challenge now is to do everything that I can to get back as quickly as possible.

"The boys have got two important, tough matches at home and my focus is to make a positive contribution to the side when I get back."

The news comes days after Brumbies vice-captain and lock Al Campbell was ruled out for 8-10 weeks after sustaining a stress fracture in his foot.
