Sri Lanka will be without Kasun Rajitha for the second Test against Pakistan in Karachi.

The paceman suffered a hamstring injury during the rain-ruined series opener in Rawalpindi and was only able to bowl six overs, dismissing opener Shan Masood as he finished with figures of 1-5.

Rajitha was off the field for much of the fifth day as the game ended in a draw, hardly a surprise result after so much time had been lost due to bad weather.

Team manager Asantha de Mel confirmed the tourists are yet to decide who will replace the 26-year-old, though a new player may not fly out to join the squad ahead of the next Test, which starts on Thursday.

The loss of Rajitha is a further blow to Sri Lanka's fast-bowling resources, though, with Suranga Lakmal missing the tour due to dengue fever.
