The former AS Monaco attacker suffered a sprained ankle during his team's 4-0 win over New Zealand - landing heavily after registering Portugal's second of the night as Fernando Santos's side made the semi-finals.
Silva has played down suggestions that he suffered a potentially serious injury, however, as he looks to play a part in the latter stages of the tournament.
Thanks a lot for all your support messages. Everything is fine with my ankle 😃👍— Bernardo Silva (@BernardoCSilva) June 25, 2017
Silva moved to Man City from Monaco on a five-year deal last month.
