The 21‑year‑old Briton used speed and power to dismantle the American, landing a clean uppercut that finished Franklin cold in round five. The win gives Itauma an 86% knockout rate and places him high in world‑title rankings.
Itauma said he would love to face unified champion Oleksandr Usyk, while promoter Frank Warren plans a July return. Franklin, stopped for the first time in 27 bouts, had previously only lost to Anthony Joshua and Dillian Whyte.
