Sri Lankan skipper Dinesh Chandimal will led the side in the upcoming Nidahas series. The Test captain hasn't been in the team's plans for T20 cricket, but he replaced by injured Angelo Mathews as captain when Sri Lanka's ODI captain had to return home early from Bangladesh with a hamstring injury. Under the captaincy of Chandimal, Sri Lanka won the tri-nation competition, Test series and the two-match T20 series. Young Sadeera Samarawickrama, one of the brightest prospects in the country was named in the preliminary squad after he smashed two half-centuries in three games for Colts Cricket Club, the same club as Mathews. The 22-year-old was excellent behind the stumps as well.
