Mauricio Pochettino has sparked fresh concerns over Ben Chilwell's fitness after revealing the Chelsea full-back was injured in Wednesday's Carabao Cup win against Bournemouth.
Nicolas Jackson's second-half strike was the difference on the night as Chelsea fired themselves to a deserved 1-0 victory over Brighton at Stamford Bridge.
The Blues boss named a much-changed side as he sought to hand more starting minutes to Mykhailo Mudryk, Cole Palmer and £115m summer arrival Moises Caicedo.
England international Chilwell also started and looked set to complete a full-match outing before limping off in the final of seven minutes of stoppage time in worrying scenes.
