Welsh rugby union player Kurt Clabby has been suspended for four years after a doping rule violation.
Clabby, 29, from Caerphilly, failed to report to for an out-of-competition test on 1 December 2015.
Clabby is banned from all sport from 28 January 2016 until 27 January 2020 and becomes the 15th registered WRU player to be on UK Anti-Doping (Ukad)'s list of banned sportspeople.
Clabby was playing in the Welsh Premiership for Bedwas at the time.
Clabby was told by Bedwas coach Steve Law that he was among four players who had to submit a sample following a training session, but could not be found or contacted by phone when the anti-doping official had dealt with a colleague.
He later claimed to have had a work emergency, but his supervisor gave evidence that he had tried to call Clabby without success before the training session.
Clabby was found to have deliberately avoided the drug-testing official to evade his test.
UKAD Chief Executive, Nicole Sapstead said: "Kurt Clabby's decision to evade sample collection is not just a serious breach of the rules but it also goes against the spirit of sport and his responsibility as a sportsperson.
"We treat violations such as this with the upmost seriousness and we will always seek to impose the maximum possible sanction on any individual who decides to consciously cheat the system."

"The Welsh Rugby Union has increased its level of anti-doping education across all levels of Welsh rugby and has invited community clubs to nominate club integrity officers to receive further guidance.
"There is no place for doping in Welsh rugby."
