Sky Sports News understands Steven Pienaar is set to miss the start of the new season through injury.
The South African international is believed to be struggling with a foot injury.
Everton have so far refused to confirm Pienaar's injury, but it is believed the problem could keep the midfielder out of action for up to six weeks.
It means Piennar will be absent for this weekend's Premier League opener with Blackburn at Goodison Park.
The news will come as a major blow for Toffees boss David Moyes who has been frustrated in his attempts to bolster his squad this summer.
