DAEGU 2011: Chambers coy about impending CAS ruling on Merritt case

From Tom Reynolds, Sportsbeat, in Ulsan

DWAIN Chambers is facing a big month. First there's the small matter of the World Athletics Championships in Daegu, then there's potentially a career defining decision from the Court of Arbitration in Sport.

The United States Olympic Committee are currently challenging a revised ruling in the Olympic Charter, introduced by the IOC after Beijing, that prevents athletes who have served a doping ban of longer than six months from competing at the Games following their suspension.

If overturned it would allow Olympic 400m champion Lashawn Merritt, back in the sport after a two-year ban that started in 2009, to defend his title at London 2012.
