Frank Lampard has explained that Michael Keane was suffering with illness in the build-up to Everton's defeat to Tottenham Hotspur on Monday evening.
The Blues were beaten 5-0 in north London after a dreadful performance, with the centre-back scoring a 14th-minute own goal to start off the rout.
The defender was withdrawn at half time, shortly after a clearance from teammate Mason Holgate had slammed into the side of his head.
