After not training a day earlier due to a tight quad from the Brisbane Test, the star left-hander had a short stint in the MCG nets on Tuesday when he received throw downs for about 20 minutes.
Head had a long conversation with Australia coach Andrew McDonald and team physio Nick Jones before going back into the rooms.
Other batters Steve Smith, Usman Khawaja and Marnus Labuschagne all had extended periods in the nets facing the likes of Mitchell Starc at full pace.
Earlier, Head had a short stint of catching practice out on the MCG, but didn't do any meaningful running.

The 30-year-old has been in rare form, smashing centuries in Adelaide and Brisbane to certify himself as India's most in-demand wicket.
Head has made 409 runs at an average of 81.80 across the first three Tests of the Border-Gavaskar series, dominating India even as the rest of Australia's batters have faced significant issues against Jasprit Bumrah.
McDonald is due to address the media on Tuesday afternoon when he will be asked about Head's fitness.
