The ICC has approved Dilruwan Perera as a replacement for Muttiah Muralitharan in Sri Lanka’s squad for the Twenty20 World Championship to be held in South Africa from September 11 to 24. The confirmation was conveyed to Sri Lanka Cricket on behalf of the tournament Technical Committee today. Perera replaces Muralitharan after medical reports were received indicating that the veteran offie had sustained an injury to his right distal bicep and would not be fit in time to take part in the event. Perera, the 25-year-old uncapped off-spinner, is the second replacement player to be called up for the tournament so far after Ben Hilfenhaus was approved to take the place of Shaun Tait in the Australian squad
