Liverpool are sweating over the fitness of Dirk Kuyt after he picked up a shoulder injury on international duty.
Kuyt is reported to have sprained his shoulder after landing awkwardly during a training session on Monday ahead of Holland's Euro 2012 qualifier with Finland.
The versatile forward has been ruled out of Tuesday's game and has been sent back to Liverpool for more tests on the injury.
Dutch coach Bert van Marwijk believes Kuyt faces several weeks on the sidelines with the injury.
"He will probably have a few weeks off and at 4pm today he will step on to the plane to Liverpool", van Marwijk told De Telegraaf.
"He pulled some ligaments in his shoulder and maybe some are torn."
Liverpool's medical staff will assess Kuyt's injury before determing the full extent of the problem.
The news will be a blow for Liverpool boss Roy Hodgson as he is already short of attacking options after missing out signing several strikers during the transfer window.
