The ICC have made a statement clearing Australia fast bowler Peter Siddle of ball tampering, after Sri Lanka's team management raised concerns during the first Test in Hobart.
The visitors approached match referee Chris Broad about the matter, though didn't make a formal complaint, and wanted the matter to be taken under investigation after the fast bowler took five wickets in the first innings.
But the ICC said on Tuesday, after Australia won the match by 137 runs: "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."
Sri Lankan team manager Charith Senanayake had told The Australian newspaper on Monday: "All that happened is we have had informal chats with the match referee about what happened about what we saw on TV - everybody saw it - and we just asked what action are you going to do about it? - that's all.
"It's unofficial, but it's on video and the whole world has seen it so let's see what action they will take."
The ICC had earlier confirmed that Broad was aware of the issue, but stated that no official complaint had been made. A statement read: "ICC match referee Chris Broad is aware of the media reports coming out of Sri Lanka on the ball issue.
"The Sri Lankan team has made no official complaint about the ball."
