Kovalev (31-2-1, 27 KO) came back last November to scorch Vyacheslav Shabranskyy and win the vacant WBO light heavyweight title, which he’d previously lost to Andre Ward. That win snapped a two-fight losing streak for Kovalev, who looked as monstrous as ever. Mikhalkin (21-1, 9 KO) is a fellow Russian and someone Kovalev considers a friend, but this is the opportunity of a lifetime for the underdog, as he’s said this week.
