London - Irish Olympic boxing medal hope Michael O'Reilly faces being sent home from Rio after failing a dope test, according to media reports in Ireland on Thursday.
Tha Irish Amateur Amateur Boxing Association (IABA) said in a statement Thursday an unnamed Irish boxer has been provisionally suspended.
"The Irish Athletic Boxing Association (IABA) has been notified by Sport Ireland today of an alleged violation of the Irish Anti-doping Rules committed by one of the boxers in our High Performance Unit," read their statement.
"In following the strict procedures applying to an adverse analytical finding, the athlete in question has been informed and is provisionally suspended.
"The boxer can request to have a 'B' sample tested but cannot participate in any competition or activity prior to the completion of an investigation under Article 8 of the Irish Anti-doping Rules."
O'Reilly, who won the European Games middleweight title last year in Baku, is slated to fight his first Olympic bout in the last 16 on August 12th after receiving a bye in the first round.
The 23-year-old further burnished his medal chances with bronze in the world championships last year.
