Wallabies winger Henry Speight won't be adding a Rio de Janeiro Olympics sevens appearance to his rugby resume after being ruled out of the Australian team because of a ligament injury to his right knee.

The Australian Rugby Union on Wednesday said the Fiji-born Speight, who has played five tests and is contracted to the Canberra-based Brumbies but took time out from Super Rugby this season to push for Olympic selection, sustained the injury in a match between the Australian sevens side and a development team.

He is expected to be sidelined for up to 12 weeks. The Olympic tournament in Rio runs from Aug. 6-11.

Speight played in the Dubai and Sydney tournaments during the 2015-16 World Rugby Sevens series, scoring two tries.
