Russian Sports Minister Vitaly Mutko told The Associated Press on Thursday that there will "not in any case" be a boycott of next year's Olympics in Rio de Janeiro.

A short time later in a separate interview, the acting president of the Russian track federation told the AP he is ready to own up to some of the charges leveled in the World Anti-Doping Agency commission's massive report on doping in the country.

"We admit some things, we argue with some things, some are already fixed, it's a variety," said Vadim Zelichenok, declining to provide further details. "It's not for the press."

The governing body of track and field is expected to rule Friday on whether to suspend Russia from competition because of the doping scandal. If Russia is banned, the country's track and field team could be excluded from next year's Olympics.
