What happened: Fabio Wardley absorbed 171 head shots from Daniel Dubois in their May meeting without being knocked down. The durability reinforced his reputation for a strong chin. The pair meet again in a scheduled rematch Saturday.

Why it matters: Durability on that scale changes rematch tactics for both fighters. Dubois needs a way to turn heavy volume into a finish, while Wardley needs to show he can manage damage across another 12 rounds.

What to watch: Watch early-round defense and shot selection for adjustments from both corners. The winner strengthens a claim toward heavyweight title contention.
