So it seems he has recovered already and now ready to fight. We do hope that this is the final push date, everyone wanted to see if Povetkin can pull it off again and upset Whyte.
Couple of sportsbooks, betbtc and cloudbet already listed this match. And the odds are favoring Whyte here - https://www.bestodds.ai/odds/sport-boxing/matchups/alexander-povetkin-vs-dillian-whyte
So yeah, if Povetkin will see the odds, hopefully he will see this as a challenge to outperform Whyte inside the ring.
