Australia can therefore still expect the destructive opener to be fit in time for their limited-overs series against England, beginning with a one-off Twenty20 at the end of August.
Finch’s availability for Yorkshire, however, is a different matter – and he seems certain to miss the vast majority of their NatWest T20 Blast campaign.
Yorkshire were hoping, even when Finch conceded he would have to sit out the remainder of the Indian Premier League after suffering the injury earlier this month, that he would be able to join them by the end of May.
Yorkshire’s director of professional cricket Martyn Moxon said: “It is disappointing news for Aaron and for us
“We were hoping that he would be with us in May but that is not going to happen. Plans are in place to fill the void that Aaron will leave.
“We are hopeful that we can get this sorted sooner rather than later and remain confident that we’ll find a replacement for the LV= County Championship and the NatWest T20 Blast.”
Today’s update from Cricket Australia (CA) has ended that prospect, and the likelihood is Finch will not be ready until the Blast knockout stages – should Yorkshire progress that far.
A CA statement explained Finch underwent surgery on his left leg in Melbourne on Tuesday.
CA physiotherapist Alex Kountouris said: “After returning to Australia injured from the IPL, Aaron had scans that confirmed a high grade hamstring injury.
“As such, Aaron was assessed by a surgeon who felt that he would have a better outcome with surgery.
“Aaron subsequently had surgery yesterday that has gone well. He will now commence his rehabilitation, and we expect that rehabilitation to take up to 12 weeks.”
Finch himself sounded optimistic on Twitter, post-operation, telling his followers: “Finished up having surgery on my hammy, 1 night in hospital but it all seemed to go very well.”
Yorkshire have already had to change their plans for overseas players once this season, recruiting Cheteshwar Pujara to help in their LV= County Championship defence after Younus Khan became unavailable because of international commitments.
Finch’s fellow Australia World Cup winner Glenn Maxwell is still on course to join them, after the end of the IPL next month, and New Zealand batsman Kane Williamson is due to arrive again for the late stages of the championship summer.
