Dominic Calvert-Lewin will miss Everton's first game of the season against Chelsea.
The striker picked up a knee injury in training this week and the extent of the knock is currently being assessed. But Frank Lampard has indicated it may rule him out of further fixtures, stating: "We’re hoping it’s weeks at the moment, but we don’t yet know that information."
The injury to the 25-year-old is a major blow to Lampard's preparations for the new campaign. With Salomon Rondon suspended for the match with Chelsea following his red card against Brentford last season, the Blues boss is without a recognised first team striker for Saturday's game.
