Russian swimmers banned for doping allegations reinstated at last minute

The fallout from the Russian doping scandal is causing havoc at the Olympic Aquatics Stadium.

The start list was altered at the last minute to add a Russian swimmer.

In the women's 100-metre butterfly, Natalia Lovtsova wasn't listed on the initial list that came out.

But she was cleared to compete in the last of six preliminary heats along with fellow Russian Svetlana Chimrova.

Lovtsova didn't swim fast enough to make the semifinals in the event, finishing in 59:19, good enough for 26th overall out of 45 swimmers in the event. She's listed as a participant in three more swim events to come.

Several other Russian swimmers were initially banned from the Rio Games because of their links to doping. But it appears they have also been cleared to compete.

Yulia Efimova, Vladimir Morozov and Nikita Lobintsev are all listed as competitors on the Russian team on Saturday. Darya Ustinova, Mikhail Dovgalyuk and Anastasia Krapivina have also apparently been reinstated, Russian news agency R-Sport reported.

Efimova posted on social media that she'd been cleared, while Morozov held a news conference Friday to say he would be swimming in Rio.

Efimova won a bronze medal in London four years ago in the 200-metre breaststroke, a race that's set to go on Tuesday.
