The SLC announced the decision with immediate effect on Friday, with the alleged incident taking place during the recently-concluded LPL where he captained Galle Marvels.
"The suspension is effective immediately and will remain in place until further notice. The test, which was conducted by the Sri Lanka Anti-Doping Agency (SLADA) during the Lanka Premier League (LPL) 2024, is part of SLC's ongoing commitment to maintaining the integrity of the sport," SLC's statement read.
"This initiative, undertaken in collaboration with the Ministry of Sports and in accordance with the World Anti-Doping Agency (WADA) guidelines, is aimed at ensuring that cricket remains free from the influence of prohibited substances." The left-hander has also been previously summoned by the SLC for his poor disciplinary record.
