Deontay Wilder's WBC heavyweight title fight against Alexander Povetkin has been postponed after the Russian tested positive for the banned substance meldonium.

Wilder was due to make the fourth defence of his crown against Povetkin in Moscow next weekend but the WBC announced on Friday that the challenger had shown an "adverse result" for meldonium when tested by the Voluntary Anti-Doping Association on April 27.
