The Warriors have suffered another major injury blow, with prop James Gavet out for up to six weeks with a broken arm.
Gavet, who has been arguably the club's most consistent front rower this season, hurt his right arm in last Friday's night loss to Penrith but no break was evident in x-rays following the game.
However, further x-rays showed a fracture in the radius after Gavet re-injured his arm at training on Wednesday.
He left that training session early - in obvious pain - and scans have confirmed his fears.
The 27-year-old joins a casualty list which includes Shaun Johnson (knee), Ryan Hoffman (foot), Albert Vete (arm), Charlie Gubb (hernia) and Nathaniel Roache (hamstring).
His absence will leave the Warriors short on firepower up front in the final quarter of the season.
Gavet has averaged more than 100 running metres per game in 2017, as well as almost 20 tackles.
He has enjoyed his most consistent NRL season, starting to deliver on the promise he showed last year.
With Gavet out, Tongan-born Chris Satae will make his NRL debut as Warrior #219 in Saturday night's 20th-round match against the Cowboys in Townsville.
The 192cm, 115kg Satae (24), who played at NYC level for Penrith in 2012, has been impressive for the Warriors' Intrust Super Premiership side this season. He made 151 metres from 15 runs in last Saturday's 28-14 win against Illawarra.
