Welsh Athletics have been hit with the news that 800m runner Gareth Warburton has been suspended from all competition with immediate effect.
The Welshman has been charged with committing violations of the UK Athletics Anti-Doping rules and as a result will not compete in the Commonwealth Games this summer.
A statement from Welsh Athletics read: "Welsh Athletics can confirm the provisional suspension of athlete Gareth Warburton after being charged with committing anti-doping rule violations under UK Athletics Anti-Doping Rules (presence of prohibited substances).
"Gareth has the opportunity to respond to the charges against him, and to have those charges determined at a full hearing before the National Anti-Doping Panel.
"Welsh Athletics strongly supports clean sport and has established a comprehensive education programme for its athletes. Welsh Athletics will not be making any further comment."
Warburton competed in the London Olympics in 2012.
