Australia all rounder Shane Watson underwent a secret fitness test at Adelaide Oval on Monday in a desperate attempt to take on South Africa this week.
The injured Australian vice-captain had already ruled out the possibility of bowling in the second Test, which begins on Thursday, greatly diminishing his chances of playing.
However, Watson showed no sign of the lingering calf strain that kept him out of the first Test in Brisbane during a 45-minute session of walking, stretching, jogging and some solid running.
Australia team physiotherapist Alex Kountouris said that Watson had pulled up well.
"He did some regulation running and got through okay so that was good. It was standard for anyone three days out (from a Test) carrying injuries," News.com.au quoted Kountouris, as saying.
"We'll mix it up tomorrow (today) and then have a full-on training session on Wednesday if all goes well. Calves are hard to rehab from so we have to make sure we don't break him down in the process,' he added.
The secret session came after confusion over whether Watson can play the second Test as a batsman only has reached extraordinary levels.
A week ago high performance manager Pat Howard insisted that if the all-rounder was unable to bowl he would not be considered.
Last Friday chairman of selectors John Inverarity countered by saying Watson would be considered as a batsman if he met strict fitness parameters. (ANI)
