Returning from the adventure, the players had complained only of aches and pains. But, more than a week after the drills finished, MacGill did not participate in his club New South Wales' training session, Sydney Morning Herald reported today.
The paper also claimed that upto four players were hurt during the exercises, which involved abseiling, day-long bush treks, mock terrorist exercises and navigating by the stars.
Cricket Australia (CA) spokesman Peter Young confirmed MacGill's injury to the newspaper, but said the safety levels during the camp were ''appropriate''.
''This was one of the main issues discussed before the camp, which in formal terms is called risk assessment or risk management.
With this program, we were conscious that we did not want to risk our elite athletes.'' ''There are a few aches and pains ... Stuart has been told to take it easy for a week,'' Young told the paper.
New South Wales coach Trevor Bayliss said at this point they are waiting to hear from the doctor about McGill's condition.
''It's really between (MacGill) and Cricket Australia at this point. It's precautionary at this stage and we're hoping he'll be right to train next week.''
