Povetkin says he is clean after Wilder bout postponed

MOSCOW (AP) Russian heavyweight Alexander Povetkin says he is clean after a failed doping test caused his fight against WBC champion Deontay Wilder to be postponed.

Povetkin tested positive for meldonium last month and the WBC ruled Sunday that his bout with Wilder, which had been scheduled for Saturday in Moscow, would be delayed for an investigation.

Povetkin says ''I'm clean. I haven't taken anything or consumed anything, so I've got nothing to fear.''

He says he took meldonium only last year, before it was banned.

Wilder's team has said the fight could be canceled altogether, but the Russian camp says it is likely to rescheduled.
