Huddersfield's England hooker Shaun Lunt will miss the rest of the season with a groin injury.
The 24-year-old, who made his England debut on last year's Four Nations tour in the southern hemisphere, has been told he needs to undergo surgery.
But, on the plus side for the Giants, half-back star Danny Brough could be back a fortnight earlier than expected.
Brough has made good progess since being ruled out for eight weeks with ankle ligament damage in early June.
He could now make his return against Bradford on Sunday week.
"Broughy's doing really well," said coach Nathan Brown. "If we were playing in the Grand Final this week, there is no doubt that he would play but it is not worth the risk at this stage."
As for the loss of Lunt, Brown admits that the early season injury suffered by Luke Robinson prevented him being dealt with sooner.
"He had a bit of slight trouble earlier in the year," said Brown. "But because we had Luke Robinson out for the first six weeks and we lost Keal Carlile after two weeks, he had to push on.
"The outcome is that unfortunately it is affecting his training and performances so surgery is the only option."
