Shishkin whooped his ass and Scull got a hometown decision in their fight. Even Shishkin is just a Euro level guy, but Scull is a straight up domestic level guy.
This is just sparring, we don't know if its true or what the circumstances was.
Scull if true could have sparred several fighters prior or anything. Conor Benn also spars like an idiot and goes full out, maybe Scull or his team figured it wasn't worth risking getting cut or injured with it being so close to his upcoming fight.
I have read something like prior the fight of Conor Benn vs Chris Eubank Jr, reading that it was rought sparring session for Scull, where Conor had gotten the better of William early on where he had dropped him in round 4-5, then didn't want to continue after 8 sparring rounds.
Benn also had sparred Denzel Bentley and Bruno Surace, but nothing much was said about that.
