David Moyes says it is ‘touch and go’ whether Kevin Mirallas will be fit enough to play against Tottenham Hotspur this Sunday.
The Belgian scored the only goal of the game in last week’s win over Stoke but was forced from the field with a groin injury 10 minutes before the end.
Moyes is already without duo Marouane Fellaini and Steven Pienaar who are both suspended.
And the Blues boss’ attacking options could be limited further should Mirallas fail to shake off his injury.
”He’s [Mirallas] been suffering from a groin strain and he is going to be touch and go,” said Moyes at his pre-match press conference on Friday afternoon.
”We are hoping that he will make it but it is by no means definite.
"Unfortunately we don't have Marouane Fellaini and Steven Pienaar and that would be a blow to anybody's team.
"We found a way of getting a result against Stoke City and it's a bit the same against Tottenham - we're going to have to find a way to get a result without two really key players."
Andre Villas-Boas will definitely be without talisman Gareth Bale, the winger having been stretchered off with an ankle problem in the final stages of Tottenham’s 2-2 draw with FC Basel on Thursday evening.
Aaron Lennon and William Gallas are also doubts with respective knee and calf injuries suffered against the Swiss champions.
