However, Portugal boss Fernando Santos said ahead of the ROI clash that he expected Silva to be available for selection against Serbia this weekend.
The 27-year-old has now been pictured in training with his international teammates, suggesting that he is winning his race to be fit for the Group A contest.
Silva has been in impressive form for Man City during the 2021-22 campaign, making 15 appearances in all competitions, while he has scored eight times in 63 caps for his country.
Portugal only need a point against Serbia in Lisbon to ensure that they claim first position in Group A and direct qualification for next year's World Cup. body check tags ::
