The 35-year-old Ukrainian proved unbeatable during the 12-round contest, maintaining his steely nerve to dominate Joshua with a series of heavy blows. 

Joshua appeared to break Usyk's momentum in the ninth round and landed a spell of punches on his opponent, before retreating into defeat. 

He was awarded a score of 115-113 from one judge, but Usyk ultimately emerged the stronger contender and earned scores of 115-113 and 116-112 

Meanwhile, Ramla Ali won her contest against Crystal Garcia Nova of the Dominican Republic in Saudi Arabia's first ever female boxing match.

The 32-year-old Ali won in a first-round knockout, improving her career record to 7-0.

After suffering his second consecutive loss against Usyk, the 32-year-old Briton picked up two of the Ukrainian's belts 

threw them out of the ring and charged towards his dressing room, before returning and taking the microphone to give an impassioned speech.
