Along with the former batsman, Ranjith Madurasinghe, Romesh Kaluwitharana, Asanka Gurusinha and Eric Upashantha have also resigned, according to a notification from the Sri Lankan Ministry of Sports.
As per a Sri Lanka Cricket official, the board has 'not officially accepted' this resignation as today evening. Until that confirmation comes through, they will continue to be in office.
Even after this acceptance of resignation, it is understood that they will be in office until the end of the Indian tour on September 6, when the visitors play their last match of the trip, which is a solitary T20I match in the capital.
Sri Lankan cricket has been on a downward curve for quite some time now. Earlier in the year, they failed to beat Bangladesh at home across series in any of the formats.
Then, they were knocked out of the Champions Trophy in England from semi-final contention by Pakistan, even if that wasn't a disappointing result on the whole.
