The fight, billed as “The Comeback,” will headline an event linked to the Esports World Cup Festival and will be broadcast live worldwide on DAZN.
It will be Joshua’s first appearance since he survived a fatal car crash in December 2025, which claimed the lives of two of his close friends.
The July contest also marks his first fight since his knockout victory over Jake Paul in December.
Saudi boxing chief Turki Alalshikh announced on Monday that the bout would form part of the Esports World Cup event.
He has also signed a new two-fight deal with Riyadh Season, with the second bout expected to be the long-awaited clash against Tyson Fury later this year.
A successful outing against Prenga could set up the November showdown with Fury.
Speaking on his return, Joshua said he used the break to rebuild and prepare for his comeback.
He said: “It’s no secret I’ve taken some time to consolidate and rebuild to be ready for stepping back into the ring, and today is the next step on that journey.
“I’m delighted to have agreed a multi-fight deal starting with July 25th in the kingdom of Saudi Arabia. I’m looking forward to competing and picking up where I left off.
“As I said, the landlord will collect his rent.
“That is certain.”
