Villa boss Graham Taylor confirmed on www.avfc.co.uk: “He’s been complaining of a sore knee and came off at half-time against Everton.
"As a precaution we’ve had it scanned and, while there’s no serious damage, a specialist has advised rest.
"As an 18-year-old who’s come a long way in recent times, it’s important that we look after Stefan and he’ll miss the trip to Highbury.”
