Australian opener Shaun Marsh will be replaced by Marcus North in the side's ongoing ODI series against Pakistan.

Marsh will return to Australia after suffering a left hamstring injury during Australia's first one-day international against Pakistan in Dubai on Wednesday.

Marsh's Western Australian captain Marcus North, currently representing Hampshire in English County Cricket, will join the Australian squad in Dubai tomorrow as a replacement player.

Australian team doctor Trefor James said Marsh underwent scans on Thursday morning, which revealed a recurrence of the left hamstring injury he suffered during the Australian summer.

"The injury means Shaun is unavailable for selection in any of the remaining games in the United Arab Emirates and therefore a decision has been made to send him home immediately in order to begin his recovery.

"Shaun's recovery process will be monitored over the next two weeks before any decision can be made on his availability for the upcoming ICC Twenty20 World Championship in the United Kingdom"

Cricket Australia National Selection Panel Chairman Andrew Hilditch said it was very disappointing to lose a player of Marsh's quality to injury.

"This is very disappointing for Shaun particularly given how hard he was worked in his recovery from the previous injury. It is however a great opportunity for Marcus North to demonstrate his talents in the one-day arena with some important series to be played in the near future.

"While Marcus has been chosen primarily as a top-order batsman, his off-spin bowling will come in particularly handy in the conditions the team will face both in Dubai and Abu Dhabi.
