Joyce: "Ngannou is a real threat."

Former interim WBO heavyweight champion Joe Joyce has assessed the level of star mixed martial arts fighter Francis Ngannou, who has recently been promoting his career in professional boxing.

The Cameroonian will share the ring with former WBA, WBO and IBF heavyweight belt holder Anthony Joshua as early as tomorrow, March 8, in Riyadh.

"Ngannou is a real threat. The guy has a very hard punch. I would rank him among the best fighters in our division. I trained with him during training camp before the Dubois fight. I went four rounds with him. He has incredibly hard punches. I would advise anyone to stay away," Metro quoted the Brit as saying.
