Reece James is out of today's match with Leeds United due to a tight hamstring.
The defender played the full 90 minutes at Tottenham last weekend and has trained with the Blues throughout the week, however he did miss Friday's session.
Potter ruled him a huge doubt for the match during his press conference on Friday, and has since stated he will definitely not feature this afternoon.
'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 us.
'There is a strong chance he will be available for Tuesday [against Borussia Dortmund] but this game comes too soon.'
