This is a good step up for Kossobutskiy who is 15-0 but has faced a fairly low level of competition so far in his career. Joey Dawejko is a well known gatekeeper at heavyweight and has faced a lot of top names in the division throughout his career.
Zhan Kossobutskiy is a good technical boxer with respectable power however Dawejko has certainly been in with bigger punchers. Dawejko will come forward the whole fight and apply pressure in my opinion.

Kossobutskiy will likely win a decision by boxing off the back foot using his technical skills. If Dawejko can make Kossobutskiy uncomfortable and force the pace he could make it interesting.
