Chelsea will be without N'Golo Kante, Matteo Kovacic and Fikayo Tomori when Chelsea visit Selhurst Park to take on Crystal Palace in a Premier League match on Tuesday night.
Kante limped off the Blues' 3-0 win over Watford on Saturday night, and coach Frank Lampard has revealed he will not be available for the match.
Kovacic, who is also nursing a minor injury will miss the clash, but might be ready for the weekend fixture.
"Kante won’t be in the squad," said Lampard. "He has a low-level hamstring injury. We’re hoping it’ll be a week or so. I would expect we’ll be very lucky to have him for Sheffield United.
"[Mateo] Kovacic trained with us today, he’s not ready for this game, hopefully, the next. [Fikayo] Tomori is still not ready. He had a small setback in training so hopefully next week,"
Chelsea will be in the hunt for a fourth victory in their last five Premier League matches, having bounced back from their 3-2 surprise loss to West Ham last week to beat Watford over the weekend.
They are currently fourth on the standings with 57 points, one behind third-placed Leicester and two ahead of fifth-placed Manchester United.
The Blues have a busy fixture as they play three matches in a space of eight matches, with Sheffield and Norwich in line after Palace.
