Nathan Patterson is facing yet another spell on the sidelines for Everton after he suffered a knock against Brighton & Hove Albion.
Patterson, who only returned from an ankle injury before the World Cup break, was forced off just after the hour mark in Everton’s 4-1 defeat to Roberto De Zerbi’s side at Goodison Park on Tuesday night.
The 21-year-old will now undergo scans to discover the extent of the problem but Blues boss Frank Lampard fears the Scotland international could be absent for 'weeks' due to damage to his medial ligaments.
