Liverpool manager Gerard Houllier says he could sign a goalkeeper on a short-term deal with Chris Kirkland and Jerzy Dudek both sidelined through injury.

Kirkland has been ruled out of action for a month with a broken finger while his Polish replacement Dudek sustained a groin injury during Liverpool's 1-0 victory over Chelsea at Stamford Bridge on Wednesday.

Dudek limped off late in the game with the club's website reporting he could be out for two to three weeks. The Polish international was replaced by Frenchman Patrice Luzi.

"I may need a new goalkeeper as Jerzy has a groin problem. We still have Patrice and, if he has to, he will fill the position well," Houllier said on Thursday.

"He came on for his debut last night and did very well, making two great saves. But we only have him available now so we might have to look at someone for the short-term."
