Doping-tainted Jamaicans out of world relays

BERLIN, (Reuters) – Five Jamaican track and field  athletes expected to run in the 4×100 and 4×400 metres relays at  the world championships have been pulled off the team, the IAAF  said yesterday.
  
Sprinters Yohan Blake, Marvin Anderson and Sheri-Ann Brooks  as well as Allodin Fothergill and Lansford Spence had tested  positive for the stimulant methylxanthine but were allowed to  race by the IAAF pending an appeal.“Jamaica will not enter these athletes,” International  Association of Athletics Federations spokesman Nick Davies told  reporters. “The news I have is that they will not be running,” he said.  
Asked whether it was a Jamaican decision to remove them from  the relay teams, Davies said: “Yes”.
  
The athletes were initially cleared by the Jamaican  Anti-Doping Commission’s (JADCO) disciplinary committee.  
However, JADCO itself then appealed the verdict saying the  substance had a similar structure to tuaminoheptane, a banned  stimulant according to the World Anti-Doping Agency. 
 
Jamaica had said a final ruling on the matter would be taken  after the Aug. 15-23 worlds, prompting the IAAF to allow them to  run as they had been cleared even though the appeal was pending.  

The world athletics ruling body warned, though, that if  Jamaica subsequently banned the athletes for doping, their  results in the relays and any medals won would be taken away.  

That would be a potential source of embarrassment for  Jamaican athletics, which has already seen sprinters Usain Bolt  and Shelly-Ann Fraser win gold in the men’s and women’s 100  metres blue riband events. 
The relay competitions start tomorrow.
