Injury may force new Everton striker Jermaine Beckford to miss out on his club debut on Saturday.
Beckford, signed on a free transfer from Leeds, has a slight leg injury which could keep him out of the first game of their Australia tour against Sydney FC.
Captain Phil Neville is definitely out as he is still recovering from the knee surgery he underwent in May.
"We've got a few players who might not play," said manager David Moyes.
"Phil Neville is carrying his knee injury so he won't be considered and we've got two or three others that I'll make a decision about on Saturday.
"So we could be without three or four of our players but none of them are serious."
