Can't see past a Beterbiev stoppage win. Mans a beast and just keeps coming at you! Smith of course has a punchers chance, probably needs to start quick and catch Artur cold, but I'd expect him to be a bit more cagey and guarded than he was against Callum Johnson for example, who he was probably underestimating and looking past in fairness.
Think Beterbiev ends it in rounds 8-10.
