Everton have been rocked by the news that defender Phil Jagielka will be out for up to six weeks with a knee injury.
Jagielka was one of three Toffees players to limp off during their 2-1 defeat to Bolton on Wednesday after he appeared to jar his knee after challenging former Liverpool striker David Ngog.
And now Everton have confirmed that Jagielka will be "probably out for up to six weeks'' with medial ligament damage.
Injuries are starting to add up for Everton as Moyes also revealed midfielder Leon Osman, one of his better players in recent weeks, also has a problem which could sideline him.
"Leon Osman has a floating bone in his knee which we think will have to be taken out and we have a few other injuries kicking around as well - Tim Cahill, Ross Barkley (knee) and Jack Rodwell (hamstring).
"Jack's had a recurrence of his hamstring injury. It is not serious but every time we get him scanned it is a grade one and very light and he comes back and doesn't feel anything.
"We maybe just need to give him a week or so longer to make sure he is right this time.''
