Nahida breached Article 2.5 for an aggressive send-off after dismissing Chamari Athapaththu, while Sarmin violated Article 2.8 for showing dissent at an umpire’s decision.
Both players also received one demerit point each, their first offences in 24 months.
The charges were laid by match officials and accepted by the players without a formal hearing. Sri Lanka won the match to level the three-match series 1-1.
