Stekelenburg worry for Netherlands
Stekelenburg has missed the last three fixtures for his club side, Roma, because of a head injury suffered in a clash with Lucio early on in his side's goalless draw with Inter Milan last month.
"The goalkeeper is undergoing further investigation following the head injury he suffered two weeks ago in the league game for his club Roma against Inter. This will show whether the goalkeeper can be part of the squad."
Netherlands, who have already qualified for EURO 2012, host Moldova on Friday before heading to Sweden four days later.
