Rugby player Ross Bevan has been banned for two years after testing positive for the use of steroids.
The 22-year-old winger joined rugby league club South Wales Scorpions from union side Nelson in February.
UK Anti-Doping (Ukad) says Bevan tested positive for the banned substance Drostanolone following a test at a squad training session on 9 February.
Under new rules Bevan could have faced a four-year ban, but his offence took place before the change was made.
Ukad director of legal Graham Arthur said the case was "unusual" and that he received the two-year ban because of the "unique circumstances" surrounding the timing of the offence.
A statement said: "Although Mr Bevan was bound by the anti-doping rules of the Rugby Football League at the time of his test in February 2015, the independent National Anti-Doping Panel concluded that, because he used the steroids in 2014, he did not intend to breach the 2015 rules.
"He did not therefore have to serve a four-year ban.
"Whilst Mr Bevan is not deemed to have acted intentionally under the 2015 rules, it is very clear that he was at significant fault."
Bevan is a product of the Rugby League Champion Schools system, having turned out for Lewis Boys of Pengam.
But he was playing rugby union for Nelson in Swalec Division 1 East when he was spotted by Scorpions assistant coach Paul Emanuelli and signed for the League One club.
