Santo Domingo.– The Dominican Olympic Committee has cleared weightlifter Yudelkis Contreras of doping allegations after her "B" sample came back negative.

Contreras was one of six athletes who competed at last year's Beijing Olympics who had tested positive for CERA, an advanced version of the blood-boosting drug EPO. The Dominican committee said Wednesday her backup sample did not show any traces of the drug.

IOC spokesman Mark Adams confirmed that the "B" sample was negative, but that the IOC was waiting for a full report from the doping lab before commenting further on the case. Contreras finished fifth in the 53-kilogram category in Beijing. She could have faced a two-year suspension.
