Dmitry Bivol fears he won't receive his $5million purse for his upset victory over Canelo Alvarez earlier this month.
The Russian dominated the pound-for-pound great for large parts of their Las Vegas clash before being awarded victory by a two-round margin. Bivol retained his light-heavyweight world title in the process after becoming just the second man after Floyd Mayweather to defeat the Mexican.
Bivol is believed to have agreed to a $5m purse, significantly less than Alvarez's previous opponents, but admitted he has yet to receive the fee due to sanctions imposed on Russia following its invasion of Ukraine. "I was willing to earn a lot less just to get this fight. I needed this fight, it was the No.1 task, he told the TASS news agency.
