Kewell to sit out South Korea friendly
Kewell pulled out to undergo further treatment on an ankle injury while David Carney, Luke Wilkshire and Danny Invincibile also withdrew.
"Harry played 30 minutes for Galatasaray last night and scored a goal when he came on as a substitute, but his ankle is not 100 per cent," Verbeek said in a statement.
"As a result it is not worth the risk of bringing Harry to Korea for the match and it is better that he receives treatment instead."
Verbeek said Invincibile had also been advised to rest because of a minor injury while Carney and Wilkshire had been given the weekend off to concentrate on their club commitments.
"Last week David Carney signed with a new club in a new country so it is more important that he settles into his new environment and start playing regular club football again,"Verbeek said.
"In terms of Luke Wilkshire, he has played plenty of football in the previous two months and unfortunately for Danny Invincibile, he picked up a back injury last week and it was not advisable for him to travel by plane for such a long time as part of his recovery process."
