Adam Swift is set to come into the side in place of Mark Percival with Matty Dawson set to switch from wing to centre.
Saints head coach Nathan Brown revealed that Gary Wheeler “should also be fit to play” but denied Saints were after revenge following their mauling at Warrington’s expense at the Magic Weekend.
“We got a great result in the first game against them and they got a great result at the Magic Weekend,” he said.
“But when the top sides play each other it only takes one team to be at the top of their game and the other not quite at the top and you can cop a bit of a touch-up.
“We’ve had to change the way we play in the last four weeks and every week it’s been about improving on the week before so that when we come to the play-offs we’re as well prepared as we can be.
“It’s impossible to say who our biggest dangers will be in the play-offs though.”
Brown added: “I think it’s more open than it’s ever been.
“So many sides can play good footie.”
