Runner Warburton out of Commonweath Games for anti-doping violations

CARDIFF, Wales -- Wales middle-distance runner Gareth Warburton is out of the Commonwealth Games after being charged with anti-doping offenses and provisionally suspended from all competitions on Wednesday.
The 32-year-old Warburton had been due to compete in the 800 meters 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 meters at the 2010 Delhi Commonwealth Games, can have the case heard in front of an anti-doping panel and said he would "fully cooperate" 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.
