The International Cricket Council (ICC) has now chose to charge Chandimal for breaching Level 2.2.9 of the ICC Code of Conduct.
The Sri Lankan board sent out a statement defending its players: "SLC advised the team to take the field to ensure the continuity of the match and wish to commend the decision taken by the team to continue with the game "under protest" to ensure the upholding of the spirit of the game".
According to a tweet from the ICC, the charge comes following a breach from Chandimal of Article 2.2.9 of the ICC's code of conduct which states that the condition of the ball had been altered by "unfair" means.
Their players protested the charge and the subsequent penalty of a ball change and the award of five extra runs to the opposition by refusing to take the field at the start of the third day's play. Five penalty runs have been added to the West Indies total.
Play eventually got under way around 11:30 a.m. after Sri Lanka team management consulted with Sri Lanka Cricket (SLC), and the visitors took the field and continued the match "under protest".
After initially appearing to be prepared to resume the match, the Sri Lankan cricketers then hesitated even as they were making their way out to the middle.
The hosts were eventually dismissed for 300 - a first innings advantage of 47 - with Devon Smith (61), Shane Dowrich (55) and Roston Chase (41) leading the way with the bat and Kamara (four for 86) starring with the ball for Sri Lanka.
The latest ball-tampering incident comes months after the infamous scandal in Newlands, Cape Town that rocked the cricketing world and led to the suspension of Australian cricketers Steve Smith, David Warner and Cameron Bancroft.
Following the drama on the third morning of the Test, SLC had released a statement backing its players.
Sri Lanka protested by refusing to leave their dressing room for almost an hour and a half.
This is the second time in two years that Sri Lanka have found themselves part of a controversy over the condition of the ball.
That match was the only Test in the game's history to be forfeited after Pakistan refused to return to the field.
