Warriors hooker Thomas Leuluai's season is over after scans yesterday confirmed he ruptured the anterior cruciate ligament in his right knee against Parramatta on Saturday.
Leuluai will have surgery after leaving the field just 23 minutes into the match. The Warriors also lost the equally experienced Ryan Hoffman with concussion in just the third minute.
Leuluai is the third player in the squad to have his campaign ended by an ACL injury. He joins Ben Henry and Ngani Laumape, who have both had knee reconstructions. The Warriors also lost three players with ACL injuries in 2013 - Henry, Sione Lousi and Steve Rapira.
Hoffman, who wasn't able to return to the field on Saturday, is following concussion protocols.
Manu Vatuvei (sternum) and Sam Tomkins (knee) are both on target to play in the Warriors' next match, against Newcastle at Mt Smart Stadium on Sunday, May 31, the first home game in five weeks.
