Akila Dananjaya faces a suspension from bowling in international cricket for a period of one year after his bowling action was found to be illegal.
Dananjaya was reported after the on-field umpires posed doubts over the extension of his bowling arm while delivering the ball during the first Test against New Zealand at Galle last month.
This was the second time the 25-year-old had been reported for his suspicious bowling style after being suspended in December for two months.
He returned to international cricket with a "remodelled action" in the home series against Bangladesh.
Dananjaya subsequently underwent an independent assessment in Chennai on August 29 after being reported again.
The tests revealed he was "employing an illegal action", resulting in an automatic one-year ban.
"As the latest report constitutes the player’s second report within a two-year period, the first of which led to a suspension, he is automatically suspended from bowling in international cricket for a period of 12 months," the ICC said in a statement.
He will have to approach the ICC for a re-assessment of his bowling action next year after the end of his ban.
Earlier, the off-spinner was one of the ten players who opted out of Sri Lanka's upcoming tour of Pakistan.
