Star attacker could miss up to nine games amid muscle tear fearsChelsea rocked by major Cole Palmer injury blowOneFootball VideosChelsea have been dealt serious setback with reports suggesting Cole Palmer's injury is far worse than initially expected. Extended absence loomingAccording to Chelsea News, the England international may face up to 6 week on the sidelines after suffering muscle tear. This would rule him out of 6 Premier League fixtures & 3 Champions league clashes leaving Enzo Maresca's side short of firepower. Despite medical clearance to return, he featured against Brentford & Bayern Munich only to aggravate the issue in the Man United match. Palmer may require surgery though Chelsea hope to avoid that outcome.
