Chelsea midfielder N'Golo Kante is out of Tuesday's meeting with Crystal Palace.
Kante picked up a hamstring injury in the 3-0 win over Watford on Saturday.
With the matches coming thick and fast he could also miss the matches with Sheffield United and Norwich over the next week or so.
Blues boss Frank Lampard revealed Kante's injury but hopes it will not keep the 29-year-old midfielder out too long.
He said: "N'Golo Kante he has a small hamstring injury, we hope it is small, that's what I've been told so far.
"But I'm guessing it will be a problem for Palace on Tuesday."
