Manchester City‘s Kevin de Bruyne is having tests on a right knee injury suffered in training on Wednesday.
City said the extent of the injury suffered by the 27-year-old Belgium midfielder is “not yet known”.
In 2016, he missed 12 games after injuring his right knee during an EFL Cup semi-final victory over Everton.
De Bruyne was City’s player of the season last term, scoring 12 goals and providing 21 assists as his side won the Premier League and EFL Cup.
City, who began their title defence with a 2-0 victory at Arsenal, next play Huddersfield at home on Sunday.
They then face matches away to Wolves and at home to Newcastle before an international break.
Their fifth match of the season is at home to Fulham on 15 September, with their first Champions League group game to take place on 18 or 19 September.
City broke several records in 2017-18, including reaching 100 points, winning 32 matches and scoring 106 goals.
