Australian captain Michael Clarke said surgery on his injured hamstring went well, as his team-mates began the second Test with India.
With Australia in the field on day one in sweltering conditions in Brisbane, Clarke was bed-ridden in his recovery from a procedure on his right hamstring - which he injured on day five of Australia's 48-run win in the series opener in Adelaide.
Clarke, 33, was in a jovial mood as he tweeted throughout the day's play, and confirmed importantly that the surgery went to plan.
"Thanks for all the well wishes. Surgery went really well. The Aust Physio @Alex_Kountouris will update the media this afternoon," Clarke tweeted.
Among his additional tweets, Clarke also noted the dismissal of Cheteshwar Pujara was "not a great decision" and that the Australian bowlers needed to make Murali Vijay play more.
