A well-built fast bowler, Dammika Prasad, was first picked to play for Sri Lanka against Bangladesh in 2005-06. He made his ODI debut against Bangladesh and created ripples by taking two wickets in successive balls. But a career-threatening back injury after that tour forced him out of cricket for a period of six months. Prasad continued to perform well on the domestic scene and was rewarded with a Test cap when India toured Sri Lanka in August 2008.
Prasad started his cricket at De Mazenod College, Kandana. He initially used to be a batsman, but was forced to take up the pace bowling duties as his school did not have anyone, who could bowl with the new ball.
