Chelsea fullback Reece James is out of today's clash with Leeds.
James will miss out with a hamstring injury.
He emerged as a doubt on Friday after Graham Potter revealed at his press conference that the 23-year-old has been struggling with tightness in his hamstring.
Potter has now revealed that James will play no part in Saturday's game, but is optimistic that he will be available when Chelsea host Borussia Dortmund in the second leg of their Champions League last-16 tie on Tuesday.
"Reece is feeling a bit of tightness which is sometimes understandable coming back from injury. We have been assessing him this week and feel it is too soon for the game today," Potter told Chelsea's official website.
"There is a strong chance he will be available for Tuesday [against Borussia Dortmund] but this game comes too soon."
