All-rounder will be in the starting XI on November 21.
Shane Watson will be in the Australia side at the Gabba in less then two weeks even if he is there strictly as a batsman only as the home side look to try and wrest the Ashes back off the England side.
The injury-prone all-rounder again sent a scare through the Australian camp when he strained his troublesome hamstring during the last one-day international against India.
He pulled up short after just one over of bowling and was unable to complete his duties with the ball.
If Watson does play it leaves just one batting slot open to Australia, with George Bailey and Alex Doolan looking likely, with the pair showing outstanding form at domestic and international level in the past month.
Australian team physiotherapist Alex Kountouris said he has assessed Watson’s latest setback after returning from India and said the prognosis was unclear at this early stage.
“Since returning home from India, Shane has been assessed and had scans on his injured left hamstring, which confirm a low-grade muscle strain,” Kountouris said.
“He will have intense treatment and rehabilitation in Sydney over the coming days and just how well he responds to this will determine how quickly he can resume full training and match preparation.
“It goes without saying that Shane and the medical team will be doing everything possible to get him fit and available for selection ahead of the first Test.
“We’ll be assessing him on a daily basis and expect to have a clearer picture of his progress later in the week.”
