South Africa captain Faf Du Plessis has been charged with ball tampering during the second Test against Australia.
The 32-year-old will face an ICC hearing after pleading not guilty.
TV footage appeared to show Du Plessis applying saliva from a mint or sweet to the ball on the fourth and final day of his side's Test win in Hobart.
The ICC said the charge related to "changing the condition of the ball in breach of Law 42.3".
"All level 2 breaches carry an imposition of a fine between 50 per cent to 100 per cent of the applicable match fee and/or up to two suspension points, and three or four demerit points," the statement read.
Du Plessis has previous in relation to ball tampering. In 2013 he pleaded guilty to one such charge during the second Test of South Africa's tour to Pakistan.
The batsman was fined 50 per cent of his match fee after being filmed rubbing the ball near the zip of his trouser pocket.
South Africa claimed victory by an innings and 80 runs to take a 2-0 lead in the three-Test series.
The third Test begins in Adelaide on Thursday.
