Chelsea head coach Frank Lampard has confirmed Hakim Ziyech sustained a hamstring injury during Saturday’s 3-1 victory over Leeds United.
The 27-year-old was substituted 30 minutes into the first half of the Premier League clash, with Christian Pulisic brought on in his place.
The Morocco international, who switch to Stamford Bridge last summer, missed the start of the campaign with a knee injury he suffered in pre-season.
But he has been in superb form since returned to fitness, scoring one goal and contributed three assists, helping the Blues cement their status as title contenders.
News of his injury will come as a major blow to Frank Lampard & co as they going into a busy period.
‘It was his hamstring, he felt it go,’ said the Blues boss.
‘We will have to find out how serious it is over the next few days, but it’s obviously disappointing going into a busy period.’
