Russia’s WBC (the World Boxing Council) Interim Heavyweight Champion Alexander Povetkin was unable to defend his belt in Saturday’s rematch against Britain’s Dillian Whyte, TASS reports.
Povetkin was defeated by a technical knockout (TKO) in the fourth round out of 12.
Andrey Ryabinsky, the head of Boxing World promotion company, said Povetkin is likely to end his sporting career after the defeat.
"I think this was the last fight," Ryabinsky wrote on his Twitter page.
