I believe their contract with Kovalev specifically states they shouldn't take a fight after June and I don't imagine Ward would fight Fonfara in 3 months.
Fonfara, as much as I appreciate him as a fighter, might win a few rounds off Ward if Ward is still a little rusty. A shutout by an even sharper Ward would be no surprise, however.
Ward easily. Ward don't lose to anyone but the three main men. Although he may just decision beterbiev. Sergey and Adonis beat ward
