The shocking loss happened after a seventh-round stoppage brought an abrupt end to his professional record at Madison Square Garden.
The British/Nigerian boxer was floored four times before the shocking fight was finally ended.
And in his first Twitter post in the wake of the defeat, Anthony Joshua shared a new photo of himself showing off his buff arm and writes: “Don’t let success get to your head or failure get to your heart.”
