Australian swimmer Isaac Cooper will miss the upcoming Birmingham Commonwealth Games for disciplinary reasons related to the inappropriate use of medication.
Swimming Australia (SA) made the announcement on Wednesday, with the 18-year-old to be sent home from the pre-Games training camp in France.
Cooper had been set to make his Games debut in four events — the 50m and 100m backstroke, 50m butterfly and 50m freestyle.
Cooper made his Olympic debut in Tokyo last year, finishing 12th in the 100m backstroke, and winning a bronze medal as part of the mixed 4x100m medley relay.
Last month at the FINA World Championships in Budapest, the Bundaberg native won a silver medal as part of the Australian mixed medley relay team, and made the final of the 50m backstroke, finishing eighth.
He also came 12th in the 100m backstroke.
"He has acknowledged his mistakes and accepted the consequences, and Swimming Australia will continue to support him as he addresses these challenges.
"The welfare of our athletes remains our absolute priority.
"Swimming Australia is vigilant in educating athletes of their obligations under the National Integrity Framework and will continue to provide all necessary support to ensure they uphold the highest standards and behaviours when representing Australia."
SA also announced on Wednesday that para-swimmer Tim Disken will miss the Games due to injury following a recent bout of surgery.
The Birmingham Commonwealth Games start on July 28.
