Aaron Finch is expected to be sidelined for 12 weeks after having surgery on his injured left hamstring in Melbourne on Tuesday. Finch suffered the injury while batting for Mumbai Indians in the IPL last Tuesday and his recovery time-frame will have consequences for his county cricket schedule: he was due to join Yorkshire at the end of May.

"After returning to Australia injured from the IPL, Aaron had scans that confirmed a high grade hamstring injury," Cricket Australia's physio Alex Kountouris said. "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. Aaron will now commence his rehabilitation and we expect that rehabilitation to take up to 12 weeks."

If the full 12 weeks is required, Finch would be unavailable until at least July, a worse outcome than Yorkshire expected. Finch was originally due to arrive at Headingley at the end of May.

"It is disappointing news for Aaron and for us," said Moxon. "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 County Championship and the NatWest T20 Blast."

Moxon later confirmed that Yorkshire "had irons in the fire" regarding Finch but the county's officials had other injury problems as their fit players sought to force a victory against Nottinghamshire.

Meanwhile, Ryan Sidebottom's calf injury will keep him out for six weeks while Cheteshwar Pujara was off the field after injuring the webbing in his left hand. Moxon, however, thought that Pujara would be fit for Sunday's match against Warwickshire.

Yorkshire supporters will not be slow to point out that their side's problems would be considerably eased if four of their players were not busy doing nothing with England in the West Indies. The county asked for Adil Rashid to be allowed to fly home in time for the Warwickshire game but that was turned down by the ECB on Wednesday.
