Anthony Joshua, a two-time world champion, knocked out mixed martial arts star Francis Ngannou in the second round of their heavyweight bout early Saturday.

Joshua knocked his Cameroonian opponent to the ground in the opening round and again more in the second in a devastating and quick display of striking power.

Ngannou, 37, a former UFC heavyweight champion, was competing in only his second professional boxing battle after losing a split decision to Tyson Fury in October.

Joshua’s fourth victory in 11 months keeps his dream of regaining the world title alive.

Eddie Hearn requested that Joshua, whom he has promoted throughout the heavyweight’s professional career, face the winner of Fury and Oleksandr Usyk.

The fight will take place in May to become the undisputed heavyweight world champion, with a rematch scheduled for later in the year.

“In five years, I won’t be fighting,” Joshua explained. “Eddie Hearn and my team will shape my future.”

With the card running over an hour later than expected, master of ceremonies Michael Buffer introduced Ngannou to the ring at 03:20 local time.

Ngannou walked down the aisle alone, dressed in a pink and white robe with gold tassels, to Drake’s song ‘God’s Plan’.

A frowning Joshua strutted confidently into the ring, his face filled with determination. He knelt in his corner and said a prayer.

Joshua had the loudest response, a mix of boos and jeers. He appeared undeterred, his gaze fixed on Ngannou.

And it was a nearly flawless start for the Watford-born fighter. Ngannou almost missed with a lead left hand, but Joshua stayed calm and composed.

AJ used his backhand to land a flush directly down the pipe. By defeating Ngannou in three minutes, he accomplished what Fury had failed to do in ten rounds four months earlier.

A stunned Ngannou stood up on the count of eight and finished the round.

Joshua has grown as a fighter in recent years, polishing his technical skills. He doubled his jab, bided his time, and waited for an opportunity.

Another right hand had Ngannou yelling on the floor. He beat the count just in time, but the outcome was inevitable.

The final punch was one that will surely take center stage in future Joshua knockout highlights.
