Shane Watson sent a scare through the Australian camp when he was hit in the helmet in the MCG nets while preparing for the Boxing Day Test.
UPDATE: Watson has returned to training with Australia on 24 December.
Allrounder Watson was struck by a short-pitched delivery from paceman James Pattinson on Tuesday morning and left the nets to receive treatment.
A Cricket Australia spokesperson said Watson was shaken otherwise okay.
In a lively session paceman Mitchell Starc also required treatment after being hit on the knee while batting.
Opener David Warner was a notable absentee from the session with his injured thumb but he is still expected to play when the third Test against India gets underway on Friday.
