Huddersfield full-back Aaron Murphy will be out for up to six weeks after fracturing a bone in his knee.
Murphy, 23, suffered the injury in Sunday’s win over former club Wakefield, in only his second appearance since moving to the Giants in the close season.
Head Coach Nathan Brown told the club’s official website: “Murphy unfortunately fractured a bone around his knee and will unavailable for around four to six weeks. He did well and the further the game went on the more he grew into the game. Murphy will get a chance again but it will just be a little later than we would have expected.
“Everyone else managed to come through the game ok and the guys that are here and not with the England squads have trained well.”
Brown has been boosted, however, by the return of forward David Fa’alogo to full training.
The 31-year-old back-rower has been recovering from the back surgery he had in the winter.
Brown added: “David is out of rehab and back in training and we will just have to see how he does but things are looking good. It is really encouraging that he is fit and that we have another able body who is ready to compete again.
“He has been out for around four months recovering from back surgery but it does mean that there are even more competition for places.”
Current Super League table-toppers Huddersfield host Castleford at the Galpharm Stadium this Friday, in a game to be televised live by SKY Sports.
