Returning from injury, Lahiru Kumara and Kasun Rajitha also featured in the squad, which was without four of the side's first-choice batters - Danushka Gunathilaka, Kusal Mendis, Niroshan Dickwella and Kusal Perera - who are unavailable owing to suspension or injury.
Binura Fernando is not expected to be fit for the ODI series, but could play the T20Is. Minod Bhanuka is likely to be Perera's replacement as wicketkeeper.
Although it is India who have arrived with a second-string squad - their Test players are on duty in England - Sri Lanka have the less experienced group of players to pick from, particularly given the absence of the suspended and injured players. de Silva has the most ODI caps, with 50. In comparison, India's captain Shikhar Dhawan has played 142 ODIs.
Sri Lanka lost all three ODI series they have played this year, going down 3-0 to West Indies, 2-1 to Bangladesh, and 2-0 to England. In T20Is, they have lost 12 of their last 13 completed matches.
