Al Nassr are playing at Iranian side Esteghlal in the last 16 of the Asian Champions League, but Ronaldo isn't in their squad despite playing 90 minutes in a 2-1 defeat to Al Orubah last time out.
Several leading media outlets have claimed this is due to a meeting with a fan in 2023, with MARCA, RMC Sport and La Nacion citing complaints from lawyers over an act of 'adultery'.
In September 2023, Nassr played away at another Iranian side Persepolis, and Ronaldo greeted disabled fan Fatemeh Hammami at the team hotel.
The artist paints portraits with her feet, and has done many of the Portuguese legend, but by touching a married woman he was contravening Iranian law.
Media reports claimed he faced prosecution in the form of 99 lashes at the time, and have again claimed that's why he's not travelling to the country, however, the Iranian embassy have told talkSPORT otherwise.

Further to their statement, the Saudi Gazette claims that Ronaldo isn't in the squad due to muscle fatigue.
In 2023, GOAL.com also quoted Hamami on the matter, refuting media claims.
