John Terry has given Chelsea a fresh injury scare to contend with as Frank Lampard also battles to prove his fitness for Monday's trip to Bolton.
The club had been confident over Lampard's recovery from a minor calf injury but manager Carlo Ancelotti admitted the midfielder's participation remains in doubt, along with that of England team-mate Terry, who has a back problem.
He said of Lampard: "He's having treatment.
"John Terry also had a little problem on his back.
"We have three days to check them. We have more possibility with Terry. Lampard, really, I don't know if he's available or not."
