South Africa all-rounder Dwaine Pretorius has been ruled out of the T20 World Cup with a fractured left thumb.

Pretorius sustained the injury during the Proteas' victory over India in the final match of the T20I series on Tuesday.

The 33-year-old will play no part in the three-match ODI series against India or the upcoming World Cup in Australia.

"The nature of the injury requires surgical intervention and Dwaine will consult the Cricket South Africa designated hand surgeon on arrival in South Africa," Cricket South Africa chief medical officer Dr Shuaib Manjra said.

"Normal rehabilitation procedures will follow to ensure he speedily returns to playing cricket."

Pretorius was the joint-highest wicket-taker for South Africa in the T20 World Cup last year.

He is set to be replaced by Marco Jansen or Andile Phehlukwayo, who were named as reserves along with Bjorn Fortuin.

South Africa had already lost batter Rassie van der Dussen due to a fractured finger.
