He sat out the defeat at Huddersfield on Saturday with a shoulder injury, sustained in the 17-17 draw against Warrington in round two.
Wane told the club’s official website: “He (Sam) got a knock on his shoulder from the Warrington game and will probably be out next week as well. It’s one of those things and we had to make a change putting Josh Charnley there and it obviously affected us moving Anthony Gelling off as well as we had to swap a few things around on top of the injuries we’ve already got so all in all it was a decent performance.
“Blake (Green) has had tonsilitis and I saw his energy dip a bit so needed to make the change with Sam (Powell). Anthony Gelling has gone, he’s done his medial ligaments so will be out for 6 weeks.”
