Chelsea midfielder Romeo Lavia walked straight down the tunnel after being substituted against Bournemouth on Tuesday night.
The Belgian lasted 55 minutes before he was replaced by Reece James, and he was reportedly accompanied by masseur Billy McCulloch as he went to the dressing room.
There is no indication that Lavia has suffered yet another injury setback but the club are clearly being cautious following his return to fitness.
Unless head coach Enzo Maresca states otherwise in his press conference later this week, the midfielder is expected to feature in Chelsea’s upcoming games.
