Russian swim star Efimova suspended over doping violation

MOSCOW (AP) World champion Yulia Efimova has been provisionally suspended on suspicion of breaking anti-doping rules.

The suspension makes breaststroke specialist Efimova, who has won four world titles and an Olympic bronze medal, the latest high-profile name caught up in the series of doping scandals that have dogged Russia over the last two years.

In a brief statement, the Russian Swimming Federation said it had received documents from international governing body FINA stating that Efimova was suspended ''in connection with a possible breach of anti-doping rules.''

The federation did not confirm reports in the Russian media that Efimova tested positive for meldonium, the same substance found in Maria Sharapova's sample at the Australian Open.

Efimova risks a lengthy ban if found guilty, since it would be her second career doping offense.
