SYDNEY- Australia batsman Shaun Marsh is to have surgery on an injured elbow next week and will miss October's test series against Pakistan in the United Arab Emirates, Cricket Australia said today.

The 31-year-old, who played in the first two tests of the series win in South Africa that put Australia back on top of the world rankings, suffered the ligament injury playing Twenty20 cricket in India.

"It's a pretty significant injury," team physiotherapist Alex Kountouris told the Cricket Australia website.

A more regular presence in the Australia one-day side with an average close to 40, Marsh is, if fit, likely to be included in the squad for the World Cup, which takes place next year in Australia and New Zealand.
