(Reuters) - Sri Lanka fast bowler Nuwan Pradeep has been ruled out of the rest of the World Cup after contracting chickenpox with selectors calling up Kasun Rajitha as a replacement, the International Cricket Council said on Saturday.

Rajitha, 26, has played six one-day internationals for Sri Lanka, taking five wickets, and made his ODI debut against South Africa in August last year. He is expected to feature in Sri Lanka's next match against West Indies on Monday.
