Australia batsman Usman Khawaja has been forced to cut short his spell at Derbyshire.
The 24-year-old was expected to spend the majority of the 2011 season at the club, however Khawaja has now been called up for the Australia A tour of Zimbabwe.
The left-hander, who made his debut for the Aussies in the fifth Test against England in Sydney, will now make his final appearance for Derbyshire in the LV= County Championship game against Kent.
Khawaja said: "I have enjoyed my time with Derbyshire immensely and wish the team luck and success for the remainder of the season.
"It is a shame that I won't be able to complete my scheduled spell in the UK but naturally I am looking forward to the A Tour and the opportunity of furthering my claims for international honours."
Derbyshire captain Luke Sutton said: "Usman has been a very popular member of the team during his short spell with the club. We are delighted that he gets this opportunity to further his claims for a place in the full Australia team."
