Wales middle-distance runner Gareth Warburton is out of the Commonwealth Games after being charged with anti-doping offences and provisionally suspended from all competitions.
The 32-year-old Warburton had been due to compete in the 800 metres at his third Commonwealth Games in Glasgow this month.
The governing body for British athletics said Warburton had been charged with anti-doping rule violations but gave no detail beyond citing the "presence of prohibited substances."
Warburton, who finished fourth in the 800 metres at the 2010 Delhi Commonwealth Games, can have the case heard in front of anti-doping panel and said he would "fully co-operate" with the legal process.
"I have not knowingly taken any banned substance ... however I recognize that the responsibility for this situation lies with me," Warburton said in a statement.
