Coach Tony Smith said: “It’s great we’re keeping players who are doing a fine job for us and helping this club advance.
“I’m big on stability in the camp within a club and we’ve got plenty of talent and experience so the blend is a good one.
“I’m confident it’s going to continue to be one of our strengths as we maintain that stability and keep the momentum moving forward at the club for the future.
“Each one of these players is a talent in their own right and has experience that they bring to the squad. The blend’s working well for us presently and I’ve got no doubt it will continue to work for us in the future.”
The news comes as a timely boost for the Challenge Cup finalists, who face Wigan on Saturday in a match which will potentially decide the destination of the league leaders shield, which the Wolves won last year.
