ANTHONY JOSHUA will be back in the ring later this year against the surprise package of 2023 - Francis Ngannou.
The former two-time unified heavyweight champion will continue his career rebuild with a lucrative Saudi showdown with the MMA man-mountain.
Promoter Eddie Hearn announced the shock deal early on Saturday morning but stopped short of revealing the date for the fight.
SunSport, however, understands the Riyadh rumble has been earmarked for March 9 - the date initially reserved for AJ's now dead-in-the-water clash with Deontay Wilder.
Former UFC heavyweight champion Ngannou shocked the world last October with a virtuoso display against WBC heavyweight champ Tyson Fury, who he dropped in the third round of their "Battle of the Baddest".
The combat sports world is abuzz with predictions for The Predator's shock opponent for his ring return.
