Liverpool have been hit with a double injury blow which will see both Stephane Henchoz and Emile Heskey out of action.
Defender Henchoz faces a lay-off of four to six weeks after being told he requires minor calf surgery.
The Switzerland international has endured a stop-start season due to injuries but played a starring role in the club's Worthington Cup final victory over Manchester United last Sunday.
Liverpool's defensive frailties this season have been attributed to the absence of Henchoz, who forms an imposing central defensive partnership with Sami Hyypia.
Striker Heskey, who was forced off during the second half at the Millennium Stadium, is likely to be out for a fortnight with a hamstring strain.
