Lampard reveals the extent of Hakim Ziyech's injury

Ziyech limped off in the first half after linking up with Reece James in the build-up to Chelsea's equalizer.

 "Hamstring. He felt it go. We will have to see over the next few days," Lampard told Sky Sports after the game.

Ziyech had to be substituted after 30 minutes during the Leeds game after an injury to his right leg.

The playmaker has settled in well since he started playing for Chelsea and has 2 goals and 3 assists this season so far.

A hamstring issue could mean a few weeks out for the attacker but scans will provide greater clarity in the coming week.
