The ACT Brumbies have been dealt another blow in a huge week of upheaval, with winger Henry Speight set to miss up to eight weeks after fracturing the front-bone in his face.

As the Brumbies come to grips with chief executive Michael Jones being stood down on Monday night, Speight will leave the club's tour of South Africa to return to Australia to meet with surgeons.

Jones has been stood down from duties following rumours about his future and a scathing interview on Saturday accelerated the board's decision to take action.

It remains unclear whether Jones will challenge the decision or ever return to his post, but it is understood the Brumbies are reluctant to sack Jones because the club cannot afford to pay out his contract.
