I believe he stopped Dubois, but not Usyk. If by stop he means Usyk’s coaches pulled him out due to Bakole trying too hard to hurt Usyk before and upcoming fight instead of letting Usyk work that could be plausible.
Sh*t happens in sparring and it doesn’t mean anything. Usyk could have done 100 rounds earlier and was dead tired and Bakole could of been fresh so I definitely could see it happened but it still doesn’t mean anything and Bakole should keep his mouth shut about what happened in the gym.
