Match officials have found no evidence of ball tampering in the Hobart cricket test between Australia and Sri Lanka and no charges will be laid.
Australia paceman Peter Siddle took nine wickets to help the hosts to a 137-run victory in the series opener but found himself at the centre of row after a picture of him apparently picking at the seam of the ball circulated on social media.
The ICC says the match refree found no evidence to suggest that the condition of the ball had been changed.
Siddle also denied any wrong doing.
Australia captain Michael Clarke was surprised at the development but equally adamant his team played within the rules.
