Manchester City players Riyad Mahrez and Aymeric Laporte have tested positive for coronavirus, the club has said.
Both players are self-isolating and neither are displaying any symptoms, a spokesman said.
They added: “Everyone at the club wishes Riyad and Aymeric a speedy recovery ahead of their return to training and the new season.”
City will skip the opening weekend of the Premier League season after being permitted to sit out the first weekend because of their late finish to the 2019/20 season due to their Champions League exertions.
City will instead feature just twice in the Premier League in September – the trip to Wolves followed by their first home match of the season against Leicester.
