Australia pace bowler Peter Siddle will not face charges of ball tampering during the 137-run win over Sri Lanka in the first Test in Hobart.
Siddle finished the match with figures of 9-104 but was at the centre of controversy after a picture circulated on social media which appeared to show him picking at the seam.
Sri Lanka team manager Charith Senanayake confirmed that he had raised concerns with match referee Chris Broad.
"The umpires frequently inspect the ball during play, and did so again after they had reviewed the video footage in question on Sunday," Broad said in a statement.
"They found no evidence to suggest that the condition of the ball had been changed.
"During the tea interval on that day, I spoke with Australia coach Mickey Arthur and told him that the umpires will continue to inspect the cricket ball regularly, and monitor the actions of all players.
"In the opinion of the umpires, there was no evidence to suggest that the condition of the ball was changed, or that the video or photographic evidence would support a charge under the Code of Conduct, so they will not be laying any charges relating to these incidents."
