Everton are sweating on the severity of a foot injury to Jack Grealish amid fears the England winger could be ruled out for a sustained period.
The 30-year-old played the full 90 minutes as Everton beat his former club Aston Villa on Sunday but has been sent to see a specialist after reporting pain in his foot.
There are fears he has suffered a suspected stress foot fracture and that the blow could keep him out for a significant length of time, which would be a bitter blow to David Moyes given how the Manchester City loanee has helped transform his team.
