Brentford full back Rico Henry was stretchered off during the Bees' trip to face Middlesbrough after suffering what appeared to be a knee injury.
He picked up the knock after a 50-50 ball between him and Boro winger Adama Traore, with the players colliding as they went for the ball.
After undergoing lengthy treatment on the field, the defender was stretchered off the field to warm applause from all sides, with Josh Clarke replacing him at left back.
Henry looked in real discomfort as he was taken off the field, and GetWestLondon will update you when we speak to Dean Smith after the game.
If the England youth international is out for any length of time it will mean B team player Ilias Chatzitheodoridis will come into the side to replace him with other left back option Tom Field on loan at Bradford.
Brentford were leading 1-0 at the time after Yoann Barbet had headed the west Londoners in front midway through the first half.
