CHELSEA were forced into a late reshuffle against Aston Villa after Levi Colwill was injured in the warm-up.
The defender, named at left-back in Friday's starting XI, pulled up before kick-off and was spotted limping down the tunnel at Stamford Bridge.
It saw Mauricio Pochettino hastily examine his Chelsea options just moments before the start of the game.
But despite having Ben Chilwell on the bench, the Blues boss instead opted to draft in highly-rated youngster Alfie Gilchrist to face Villa.
Chelsea will now be sweating over Colwill's fitness ahead of Wednesday's trip to Liverpool.
The 20-year-old has been a regular face in the team this season and already has 27 appearances to his name.

Colwill was a target for multiple clubs including Liverpool last summer.
But after returning from an impressive loan spell at Brighton, he opted to pen a long-term contract with Chelsea instead.
