The Juventus forward has strenuously denied accusations made by Kathryn Mayorga that she was raped by him in a Las Vegas hotel room in 2009.
The ongoing scandal is not the reason for his absence, however, with Portuguese newspaper A Bola reporting that he has asked to be left out of the side until 2019.
Cristiano Ronaldo, shown here at this year's World Cup, won't be playing for Portugal in the immediate future.
Portugal coach Fernando Santos said Ronaldo also will not be called up for the next round of global games in November.
The Juventus star, who has scored 85 times in 154 appearances for his country, has not been selected for the Nations League match against Poland or the friendly against Scotland.
"Keen as I may be to clear my name, I refuse to feed the media spectacle created by people seeking to promote themselves at my expense".
Few days back as well, the Juventus player denied raping an American woman in a Instagram live video and called it fake news. "For the next two squad selections, this one and the one next month, Ronaldo won't be with us".
Santos said Ronaldo will also not be called up for November's worldwide games.
The 33-year-old superstar reportedly met with Portugal coach Fernando Santos and Portuguese federation president Fernando Gomes and collectively agreed it was best for Ronaldo to step away for a few games.
She had initially filed a police report describing the alleged crime - but didn't identify Ronaldo by name. Mayorga, however, contends in her lawsuit that both a nurse at the hospital and a Las Vegas police detective discouraged her from filing charges against Ronaldo because of his fame.
