Birmingham Bears have signed Chris Green, the offspinning Sydney Thunder allrounder, for the remainder of the Vitality Blast group stage.
Green is yet to make his international debut, and so falls short of the required games needed for an ECB governing body endorsement for a visa, but is eligible thanks to a British passport via his mother.
While he has regularly played for Surrey's second XI during stints in club cricket for Sunbury, this will be Green's first stint as a first-team overseas player for a county.
Green has been playing in the Global T20 in Canada, where he took 11 wickets in five games for Toronto Nationals, and is expected to join up with the squad for tonight's game against Nottinghamshire despite playing in last night's defeat against Winnipeg Hawks.
He will be available for the seven remaining group games, before joining up with Guyana Amazon Warriors for the start of the Caribbean Premier League.
Paul Farbrace, the club's sport director, said: "We're naturally delighted that we have been able to bring in a player of Chris' talent and experience at such short notice.
"As an offspinner, Chris is quite unique by having a lot of experience of bowling his overs at the top of the innings, in the powerplay. As a batsman, he also has the ability to clear the ropes, which will gives our middle order more depth and firepower.
"We all look forward to welcoming him to Edgbaston as a Bear, and hopefully helping us reach the knockout stages."
Green, 25, has yet to make his first-class debut, but has played 57 T20s after breaking into the Thunder team in the 2015-16 Big Bash.
Birmingham Bears have had a mixed start to the Blast, sitting sixth in the North Group but with a game in hand on fourth-placed Leicestershire.
