Due to sanctions imposed on the Russian Athletics Federation following a high-profile doping scandal, Provorov and other Russian hockey players competed at the 2021 IIHF World Championship as the Russian Olympic Committee (ROC). Provorov's first point in the tournament came from an assist in the final moments of the Group A opener against the Czech Republic. He picked up another assist in the same round against Switzerland, helping clinch a playoff berth for the ROC. The Russian team eventually fell to Canada in a quarterfinal overtime match, finishing fifth overall.
