Cristiano Ronaldo has been provisionally suspended by the Portuguese Football Federation (FPF) after leaving his country's international camp last month.
The 41-year-old captain walked out of Portugal's Nations League squad in September after being an unused substitute against Norway and then finding out he would not start against Denmark.
In a lengthy statement, the Al-Nassr forward later explained he left because Portugal coach Jorge Jesus twice "broke his word", accusing him of an "absolute breach of trust".
In a statement, the FPF said a "provisional suspension" was issued on 9 October and they had marked the case as "urgent".
The FPF's rules state any player who fails to appear or walks out on international duties faces a ban of one to six months, as well as a fine.
Pedro Proenc, president of the FPF, told Portuguese outlet Record:, external "This is a time for calm and composure. We are all sitting down together at the table.
"There is a strong desire to have our captain back with us. There will be a normal disciplinary process."
