Lavia has endured an injury-plagued time with the Blues since joining from Southampton for £53million plus add-ons in August 2023.
“It's a muscle problem,” Maresca reiterated on Friday morning. “We don't know yet when he can be back.”
Pushed on whether Lavia is expected to be a short-term or long-term absentee, Maresca replied: “We don't know.”

Maresca also confirmed that Chelsea avoided suffering any fresh injuries from their miserable trip to Leeds on Wednesday, when the Italian made five changes to his starting line-up from the draw against Arsenal and his side delivered one of their worst performances of the season and lost 3-1.
Caicedo sat out of the Leeds game as he began his three-game league suspension following a red card against Arsenal. He is also suspended against the Cherries and on December 13 against Everton.
