SYDNEY:-Ryan Harris needs surgery on his troublesome knee but the Ashes hero said he will delay the operation tour to South Africa tour next month. Harris, who has rarely lasted a full series, considered having surgery during the Ashes but it would have ruled him out of last two Tests. Instead, he played through pain and bagged man-of-the-match award in the final Test. "There's bits of bone floating around (and) we were thinking about doing it then and there and missing the rest of the series," he told reporters.–Reuters
