Chelsea have been handed a huge injury scare with Levi Colwill forced off against AFC Wimbledon on Wednesday night.
The 20-year-old has played every minute of the Blues' opening three games of the Premier League season and started tonight's Carabao Cup second-round clash at home to the League Two side.
Colwill appeared to be struggling around the hour mark and was replaced by Malo Gusto after initially attempting to carry on.
Rather than taking his place on the substitutes' bench, Colwill was immediately assessed by a club physio and then walked down the tunnel in the direction of the dressing room.
An injury to Colwill will be a huge concern for both Pochettino, who already has 10 players unavailable.
England manager Gareth Southgate will also be keen to learn of any injury, with Colwill expected to be part of his next squad which will be announced on Thursday ahead of Euro 2026 qualifiers against Ukraine and Scotland.
