Diesel shared the news on Instagram, posting a picture with Ronaldo and stating a role was written for the highest-scoring player in world soccer history.
This would mark Ronaldo's debut in a feature film, as he has no previous acting experience.
Diesel also hinted at the potential return of Paul Walker's character, Brian O’Conner, despite the actor's death in 2013.
The method for O'Conner's return remains unclear, with speculation suggesting digital insertion.
