Joel Robles will continue in goal for Friday’s trip to Hull City.
Everton are set travel to the KCOM Stadium with the same squad that was available for the 2-0 victory over Leicester City on Boxing Day.
Maarten Stekelenburg has not resumed training after sustaining a dead leg in the Merseyside derby earlier this month, meaning Joel is due to make his third Premier League start of the season.
James McCarthy, meanwhile, has also been ruled out with a hamstring problem, although Koeman confirmed the Republic of Ireland international has now resumed light training.
“Stekelenburg has not yet joined training and won’t be available,” said Ronald Koeman. “I was really pleased by the performance of Joel against Leicester.
“Stekelenburg is not running yet. His dead leg is still painful and we need to wait until he is fully ready to join training. Maybe it will be in two or three days’ time, but he is not yet ready.
“I was very happy about Joel’s performance [against Leicester]. I think he played well and made two or three interceptions from crosses in the second half.
“He showed that confidence to the rest of the defenders and the whole team’s defensive organisation was very good.
“Leicester did not create too many chances and Joel was a part of that.”
Offering an update on McCarthy, Koeman added: “He is starting training out of the group, but it will take maybe 10 more days until he’s fit to come back for the team.”
Bryan Oviedo will also be missing for the clash with Hull, while Yannick Bolasie and Muhamed Besic continue to be sidelined with long-term knee injuries.
