Sri Lanka have named Angelo Mathews as skipper for shortest format of the game after Lasith Malinga stepped down from the post ahead of World T20.
Malinga, however, has also been undergoing slow recovery from knee injury which he sustained during the West Indies series last year.
With the resignation, all -rounder Mathews, who captains Sri Lanka in ODIs and Tests, will now lead the side in all the three formats of the game.
De Silva, however, said that the Malinga has only left the captaincy role and he would continue to remain in the squad, Sport24 reported.
Earlier, Malinga had hinted that he might call curtains on his illustrious international career at the end of the T20 pinnacle event.
Sri Lanka will play their opening World T20 match at Eden Gardens in Kolkata on March 17.
