Sport Ireland are reviewing the James Cronin doping violation.
The Munster prop was banned for a month after a sample taken in November showed traces of two banned substances.
Cronin put their presence down to a dispensing error at a pharmacy.
Sport Ireland CEO John Treacy says they’re reviewing the case, which could end up with them appealing.
Meanwhile, Sport Ireland’s 2019 anti-doping figures showed a total of seven violations.
There were five adverse analytical findings, while the balance were "anti-doping rule violation cases".
Three of the seven have been announced, while four are pending.
Marking the 20th anniversary of the Irish Anti-Doping System, Sport Ireland today published its annual Anti-Doping review.
It provides a full and detailed account of anti-doping activities across 2019.
