Warriors fullback Sam Tomkins will be sidelined for up to six weeks after tearing his posterior cruciate ligament in his left knee.
Tomkins left the field 11 minutes into the second half of Saturday's third-round victory over Parramatta at Mount Smart Stadium and scans have revealed a partial tear of the posterior cruciate ligament in his left knee.
He's expected to be available again later in April or early in May.
The coach Andrew McFadden says the outcome is a lot better than it could have been.
Tuimoala Lolohea will get the first opportunity to replace him in the fullback jersey and McFadden says it's a big chance for him.
McFadden says the 20-year-old has special ability and says he has great confidence in him.
Tomkins joins an injury list which still includes Sam Rapira (hamstring), Konrad Hurrell (knee) and Ngani Laumape (knee).
