Reece James, Jorginho and Timo Werner have doubts for Chelsea ahead of the game against Watford on Wednesday night.
The trio were all involved in the 1-1 draw against Manchester United on Sunday, but now they need pre-match checks at Vicarage Road.
Thomas Tuchel will also be without Ben Chilwell, Mateo Kovacic and N’Golo Kante, although Romelu Lukaku is available. Lukaku had no reaction to his return to action after his spell on the sidelines that followed his ankle injury.
Asked about Chelsea’s fitness status, Tuchel said: “It’s easy with Romelu. He came in (against Man United) and kept training.
“There was no reaction from his injured ankle so he’s been in training and ready to go in minutes.”
When asked who will be absent, Tuchel replied: “Sure Chilwell, Kovacic and Ngolo. We have some doubtful players, maybe we need more time, more tests to reassess the situation.
“It’s Reese James, Jorginho and Timo Werner. They all trained with us. There will be some last minute decisions on all three.”
Chelsea leads the Premier League, one point behind Manchester City in second place.
