Aston Villa striker Emile Heskey has been ruled out for up to a month with a medial knee ligament injury.
The 32-year-old former England player, who has scored four goals this season, suffered the setback in training on Wednesday and will require surgery.
Heskey has shown good form since Gerard Houllier, who he played under at Liverpool, took charge in September.
John Carew is now the club's only fit senior striker available for Saturday's Premier League match at Fulham.
The injury to Heskey comes while England international forward Gabriel Agbonlahor is still recovering from groin surgery, though England under-19 striker Nathan Delfouneso will be available to face the Cottagers.
"Heskey tore the medial meniscus in his right knee yesterday in training, with no other player involved in the incident," read a club statement released on Thursday.
"The injury will require an operation and he faces between three to four weeks out of action."
After 62 caps and seven goals, Heskey quit international football following England's disappointed World Cup campaign this summer.
