Kovalev's confidence is just not the same anymore and neither do I think his chin is. He took some brutal punishment from Ward and it was already bad in the first fight which didn't have a KO (Kovalev got jelly legs and stuck his head out between the ropes to avoid further punishment at one point). Kovalev's career is finished and I doubt he will beat Shabransky... RIP Kovalev.
It's gonna be a tough road for Sergey Kovalev without John David Jackson.

I hope so. He's one of the very worst human beings in boxing. Pure and utter scum. He's right up there with ODH, and Amir Khan as complete and utter embarrassments
