Michael Phelps has been suspended from swimming following his recent DUI arrest, as the sport's governing body told him to dry out for the next six months.
USA Swimming suspended the 18-time Olympic champion, dealing a blow to his comeback and forcing him to withdraw from the 2015 world championships.
After Phelps' DUI arrest, the 29-year-old is banned from USA Swimming-sanctioned meets through April 6 for violating the official Code of Conduct.
Its executive committee approved the sanctions, which take effect immediately.
"Michael's conduct was serious and required significant consequences," said Chuck Wielgus, executive director of USA Swimming, in confirming the ban.
"We endorse and are here to fully support his personal development actions."
Michael is headed to a rehab program to better understand himself, the superstar athlete announced in the wake of his arrest, whatever that means.
