Welsh Athletics has vowed to carry out an internal review after a second drugs scandal hit its team at the Commonwealth Games.
European 400 metres hurdles champion Rhys Williams, the co-captain of Wales' athletics squad in Glasgow, has been provisionally suspended and will miss the event after failing a drugs test.
The 30-year-old son of rugby union great JJ Williams becomes the second Welsh athlete to be forced out of the Games over an alleged doping offence, after 800m runner Gareth Warburton was withdrawn nine days ago.
Williams said he was "utterly devastated" by the news of his failed test and insisted, like Warburton, that he had never knowingly doped.
Williams, who also took bronze at the Commonwealth Games in Delhi four years ago, said he was shocked to test positive.
Welsh athletics chief executive Matt Newman said "we just hope we can back up what the athletes suspect is the source of the contamination."
Another Welsh athlete is out of the Commonwealth Games on a doping charge.
Team Wales announced the withdrawal of athlete Rhys Williams after being charged with committing an anti-doping rule violation.
Team Wales says the violation under the IAAF Anti-Doping Rules followed an in-competition test at the Glasgow Grand Prix on 11 July 2014.
It says Williams will have the opportunity to respond to the charges against him at a full hearing before the National Anti-Doping Panel.
