Despite the Frenchman having to be withdrawn at half-time against Manchester United, the Toffees boss is wary of bringing his captain back into action earlier than is safeEverton manager Roberto Martinez has no intention of rushing Phil Jagielka back into action despite Sylvain Distin's injury.
Distin picked up a suspected hamstring problem during Sunday's 2-0 victory over Manchester United at Goodison Park and was replaced by Antolin Alcaraz at half-time.
The injury to the veteran Frenchman leaves Everton with just two recognised centre-backs available, in the form of Alcaraz and John Stones.

"Phil Jagielka has got his own programme and it is important that we follow that and we don't rush him back," the Toffees boss told the club's official website.
"He has been involved with the first team training now and that is a really good sign. We want Phil back as quick as we can but not because we have got an injury with Sylvain.
"We aren't going to rush and do the wrong things in his individual programme.
"Phil is going to be fully fit very soon and I do expect that he will probably be able to make the squad against Manchester City and that's always been the plan. I do believe that we will be able to reach that."
Everton are locked in a battle for the last Champions League qualification spot in the Premier League, sitting one point adrift of fourth-placed Arsenal with just three matches remaining.
