Owens has moved to Langtree Park in the off-season, having signed from Widnes Vikings in which he played 18 times, scoring nine tries as well as kicking goals in 2015.
“Jack’s been running at fullback all pre-season; he’s been phenomenal. He’s a great recruit and somebody we’ve followed closely for a while,” Cunningham told the Liverpool Echo.
“I’m still shocked that Widnes let him go, I honestly am. It’s definitely our gain. We’ve put lots of education into him and he’s loving being around, it’s a different environment and everybody’s challenging him. He just loves it.”
With Owens now taking the vacant fullback spot from Jonny Lomax, Cunningham has said he is not setting a date for Lomax’s return, and that the club need to be careful in terms of avoiding a reoccurence.
“I’ve not given Jonny a timeframe. Obviously he’s coming off a recurrence of that injury, when Jonny’s ready he’ll be ready,” he said.
