Nottinghamshire have brought in Bangladesh opener Tamim Iqbal as a short-term replacement for overseas player David Hussey.
The experienced Australia batsman will return to his homeland after Sunday's Friends Life t20 clash with Lancashire to prepare for the one-day international series against Sri Lanka, and Tamim, 22, has agreed terms to deputise for the six subsequent fixtures.
His signing is subject to approval from the Bangladesh and England and Wales Cricket Boards.
"David has been excellent for us and he still has a lot to offer to the Australian team," said Notts director of cricket Mick Newell.
"His contract with us was always subject to international commitments and I'm pleased that we have been able to secure a quality replacement.
"Finding quality overseas players at short notice is always a challenge but we are very pleased to have agreed a deal with a player of Tamim's quality.
"He's an exciting player who has established himself on the international scene at a young age and he is already assured of a long Test career."
Tamim averages 40.13 in Tests and has a reputation as a fluent scorer, with an international Twenty20 strike rate approaching 100.
"It has been a dream come true in every sense as I have longed to play county cricket ever since I became a professional cricketer," he said.
"I have enjoyed every moment whenever I have been in the UK in the past and it is a privilege to be part of such a great club like Nottinghamshire, which has an awe-inspiring tradition and character.
"I am very excited to take the field and perform and help with Notts' mission of winning the Friends Life t20."
Notts were fined £600 on Tuesday after they were found not to have registered Hussey for their opening win over Derbyshire, in which he scored 60.
Hussey's compatriot Adam Voges will captain the side for the remainder of the competition.
