Everton forward Bernard could be out of action for a considerable chunk of the season after damaging his medial knee ligament in Saturday's 3-2 loss at Brighton.
Half an hour into the contest at the Amex Stadium, 27-year-old Bernard collapsed to the floor with no one around him. Following treatment from the Toffees medical staff, he was withdrawn and Gylfi Sigurdsson came on in his place.
Everton were level at 1-1 when Bernard was forced off, with Dominic Calvert-Lewin's composed finish giving the visitors the lead inside the final 20 minutes. However, a Neal Maupay penalty and Lucas Digne's stoppage-time own-goal saw Brighton turn the game on its head.
