The International Weightlifting Federation is seeking "further clarification" from the International Olympic Committee and the World Anti-Doping Agency before making a decision on which Russian athletes can be cleared to compete at the Rio de Janeiro Games.
The Budapest-based IWF says that "some points might lead to confusion" regarding the IOC ruling giving individual sports federations the responsibility of deciding who can compete in Rio.
The IWF said no Russian weightlifter sanctioned for doping will be allowed to compete — even if they had already served their suspension — and that it is waiting for evidence from the Russian athletes entered for Rio before making its decision.
