Briton Anthony Joshua delivered the most powerful statement to the heavyweight division with a destructive second-round knockout win over Francis Ngannou in Saudi Arabia.
Joshua, 34, floored the UFC champion in the first round and early in the second.

The 37-year-old appeared to be out before he even hit the canvas and required medical treatment.
