Parramatta copped a triple whammy on Friday night, suffering a heavy loss to rivals Canterbury and potentially losing key men Corey Norman and Danny Wicks for an extended period.
Norman, playing fullback in the absence of Reece Robinson (fractured cheek), went down three quarters of the way through the game and had to go off with a knee injury which coach Brad Arthur said was a suspected posterior cruciate ligament strain.
PCL strains are typically a four to six week injury.
"He'll have to have scans, I'm not sure," Arthur said.
"They're saying [it's a PCL] so that's better than an ACL. I'm not sure but I wouldn't think [it's a season-ending injury]."
Norman has been arguably Parramatta's best player this year at both five-eighth and fullback and his absence even for a month would cruel Parramatta's dim hopes of making a late charge for the finals. However his loss is likely to be partially alleviated by the return of Robinson next round.
Arthur said prop forward Wicks – who came off the bench in the 26th minute before being substituted off in the 47th and not returning – had been carrying a major shoulder injury that requires surgery.
"Danny Wicks, shoulder, he's been carrying that for a long time now, it's at the stage where he can't lift it, so he's probably an operation now," Arthur said in an indication Wicks may have played his last game for 2015.
Forward David Gower also has a knee injury that will need to be assessed while Junior Paulo required a concussion check during the game and halfback Chris Sandow had had a hamstring scare at training, but none were thought to be serious.
