Thomas Tuchel has said that Reece James must undergo examination ahead of Chelsea's clash with Norwich after suffering a setback.
The Blues star made an impactful comeback from his hamstring injury featuring in consecutive games against Liverpool, Luton Town and Burnley, recording a goal and assist against the Clarets.
However, James could only manage 70 minutes on the pitch at Turf Moor and it turns out he was feeling some discomfort during the match, and has missed first team training since.
