NAGPUR - Sri Lanka have lost key spinner Rangana Herath for the crucial third Test against India starting Saturday because of recurrent back problems. The tourists on Tuesday called up Jeffrey Vandersay to replace the 39-year-old for the New Delhi Test, which Sri Lanka must win to avoid another series defeat. "We have recalled Herath and he will return immediately as we decided to rest him", selectors' chairman Graeme Labrooy told reporters. "Herath will be replaced by Jeffrey Vandersay", Labrooy added. The veteran Herath bowled 39 overs in the second Test.
