The fact that the event is part - promoted by GBP (of which Hopkins is a shareowner), and being officiated by 4 American officials tells me that the deck is stacked against Kovalev and he will not receive a fair shake .
With 3 American judges Kovalev must absolutely dominate rounds to win them. Any close, competitive, non eventful rounds will automatically go to BHOP.
With an American ref Hopkins illegal antics (intentional headbutt, hitting after the bell, overexagerating nonfouls) will be encouraged and permitted.
Kovalev is promoted by Kathy Duva, managed by a guy "Klimas" . They are both great for Sergey and I believe they're acting in Sergey's interest. But I feel they should have requested 3 international judges.
All of these things put Kovalev at a disadvantage.
Anyone can be knocked out though (yes including old man BHOP) and I do believe Sergey can do it if he fights smart.
For what it's worth - Paul Malignaggi is predicting a Kovalev KO win...
