Liverpool have confirmed that versatile Dutch forward Dirk Kuyt will be out of action for around a month after suffering a shoulder injury while on international duty.
The 30-year-old suffered the injury during the Netherlands' 5-0 victory against San Marino on Friday, landing awkwardly as he stretched to reach a cross.
He has already returned to Merseyside to be assessed and the prognosis is four weeks on the sidelines.
Dr Peter Brukner told the club's official website:"Dirk has damaged his shoulder at the A-C joint, which is between the collar bone and the shoulder.
"He is likely to be out for four weeks."
Meanwhile, former Reds boss Gerard Houllier is expected to return to English football to take charge at Aston Villa later this week.
Houllier, who was at the helm at Anfield between 1998 and 2004, is also expected to name former Liverpool legend Phil Thompson as his number two.
