Athletics: Doors shut on Gatlin's coach

Trevor Graham, the controversial coach of sprinter Justin Gatlin, will not be allowed to use US Olympic facilities because of his record of mentoring athletes who have used performance-enhancing drugs. US Olympic Committee chairman Peter Ueberroth said the move was "based on the unusual number of athletes he has coached who have been convicted of doping offences". Graham has denied any knowledge of doping by his athletes, although six of them have served drug suspensions.
