Warriors prop and second rower Steve Rapira is out for the season after he ruptured the ACL in his right knee last weekend.
Rapira will have surgery after suffering the injury while playing for Auckland Vulcans in their New South Wales Cup match against the Mounties.
It's another cruel blow for the younger of the club's Rapira brothers.
He was in the playing squad for each of the Warriors' first three matches of the NRL season but lasted only four minutes of the third-round clash against the Cronulla Sharks on March 24 before being forced off with an ugly ear wound.
After recovering from plastic surgery to repair the damage, Rapira was making his return in the New South Wales Cup last Saturday.
