Doping-tainted Jamaicans out of relays

Five Jamaican track and field athletes expected to run in the 4x100 and 4x400 meters relays at the World Championships have been pulled off the team, the IAAF said on Wednesday.

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," IAAF spokesman Nick Davies said.
