Mateo Kovacic is the latest Chelsea midfielder to come a cropper after suffering an inflamed Achilles tendon in the draw with Sheffield United.
It means there are now SIX midfielders out of action for the Blues – making Frank Lampard very thankful for the international break.
Croatia will be without Kovacic for their Euro 2020 qualifiers against Hungary and Slovakia because of this latest injury.
He is currently being assessed, but Chelsea are at risk of losing one of their star performers of the season so far for the September 14 trip to Wolves.
A drab season on loan at Stamford Bridge meant the reaction to his £40million permanent move from Real Madrid was somewhat understated.
But the 25-year-old’s absence will be keenly felt if none of the Blues’ wealth of injured midfielders can get fit.
Ruben Loftus-Cheek remains unavailable with an Achilles problem suffered in May, the same issue currently plaguing Callum Hudson-Odoi.
And neither player is set to be fit for a few weeks at least, although Hudosn-Odoi is thought to be ahead in his recovery.
Like Kovacic, N’Golo Kante will sit out the upcoming international fixtures having sprained his ankle.
Lampard hopes the Frenchman can feature in a fortnight but Marco van Ginkel is much further away from playing due to a long-term ACL issue.
Finally, winger Pedro felt his hamstring in the warm-up to the win over Norwich and missed the subsequent draw with Sheffield United.
For many Chelsea fans, Kovacic’s injury is the straw that breaks the camel’s back.
