This isn’t a good fight and is hopefully not a sign of things to come for Johnson who is an exciting fighter. Emurlaev recently came back to the sport after a long lay off and hasn’t looked good since coming back. Johnson is a powerful light heavyweight who will either get knocked out or knock his opponents out.
I don’t expect Johnson to struggle here as he’s simply levels above Emurlaev who can compete in the domestic Russian scene but will fall apart quickly when he steps up at this stage of his career. Johnson should win by knockout within five rounds due to his power and explosiveness.
