- Henri Lansbury came off injured early into the second half against Derby on Saturday and is a doubt to face Chelsea in midweek. Pelly-Ruddock Mpanzu is on standby to deputise.
- Luke Berry, Jordan Clark and Sonny Bradley are still injured for the Championship outfit.
- Danny Hylton has scored in back-to-back matches and was the WhoScored Man of the Match from the bench against Derby at the weekend. He will push for a rare start here.
- Chelsea have to get over Carabao Cup disappointment quickly as now they have the FA Cup to prepare for on Wednesday. Thomas Tuchel will make wholesale changes given the sharp turnaround from Sunday's penalty cut shoot-out defeat at Wembley.
- Cesar Azpilicueta came off against Liverpool with a knock and is unlikely to be risked here, while Hakim Ziyech missed out completely after an injury suffered in the Champions League last week.
- Romelu Lukaku has been benched for Chelsea's last two matches but will lead the line against Championship outfit Luton on Wedensday. Kepa was brought on for penalties on Sunday and ended up missing the decisive spot kick that lost it for Chelsea but he will start here.
- Reece James made his comeback from injury against Liverpool after two months out and will get more minutes here. Andreas Christensen and Ben Chilwell will continue to miss out here.
