Saturday's bout between Joe Smith Jr. and Maxim Vlasov for the vacant WBO light heavyweight world title has been postponed due to a positive COVID-19 test.
Smith and Vlasov had been due to headline Saturday's Top Rank event at the MGM Grand in Las Vegas but the fight has been postponed after Vlasov returned a positive test.
"I am devastated with the postponement of my world title fight against Joe Smith Jr. I have been following strict protocols, I have done regular testing with negative results, and I have no symptoms," Vlasov said.
"I am well prepared and had an excellent training camp. I look forward to the rescheduling of the fight and the opportunity to display my world class skills."
The Richard Commey-Jackson Marinez lightweight bout has been elevated to the main event. It will take place over ten rounds and a win would propel Commey towards another World Title shot in 2021.
