Aaron Finch 's disastrous Twenty20 campaign for Yorkshire has been confirmed as over after scans revealed that he has broken his foot.

Finch has fractured his fifth metatarsal in his right foot. He will return to Australia on Tuesday to see a specialist in Melbourne.

The Australia Twenty20 captain picked up the injury during Yorkshire's NatWest T20 Blast victory over Durham Jets last Friday at Headingley.

The injury continues a run of misfortune. He tore his hamstring playing in the Indian Premier League, which kept him sidelined for two months at the start of the summer and last month he bruised his lung when he was struck by a bouncer while playing for Yorkshire's Second XI in an attempt to find his way out of a mediocre run of form

"That's the end of the season for Aaron, as far as Yorkshire is concerned," said director of cricket Martyn Moxon. "It is a great disappointment for Aaron and the club and we wish him a speedy recovery."

Yorkshire will seek to extend Glenn Maxwell's stay to cover for Finch. The Australian batsman plays his last match for the club this evening before a two week tour of India with Australia A.

"The plan is for Glenn to return after the India A tour at the back end of July to play in the Royal London One-Day Cup competition and a couple of Championship matches," Moxon said. "We are finalising arrangements with Cricket Australia, but expect that to be sorted out soon."

New Zealand's Kane Williamson will join the Club for the final four games of the Championship campaign at the end of August.

Finch made only 76 in six innings for Yorkshire and sat out their defeat on Sunday against the bottom club, Derbyshire, which saw their hopes of a stealing quarter-final place hanging by a thread. Any failure to beat Worcestershire at Headingley on Tuesday would see Yorkshire eliminated at the group stage.
