Watford striker Grzegorz Rasiak has been ruled out for around a month with a groin injury.
The Poland international was carried off on a stretcher during the win over Nottingham Forest last week and missed the 2-2 draw with Sheffield Wednesday at the weekend.
Manager Brendan Rodgers said: "He actually tore his abductor, which is a tissue injury and needs time to heal and is part of the recovery process."
