Stats over the last 6 encounters
St Helens are set to welcome back scrum-half Matty Smith from a broken leg, which will enable skipper Jon Wilkin to revert to loose forward in place of Morgan Knowles, who is ruled out with a knock sustained in the win over Catalans Dragons.
Warrington Wolves are boosted by the return of full-back Stefan Ratchford for his first game of the season while prop Dom Crosby is also back in the reckoning. Toby King and Jack Johnson are replacements for injured centre Ryan Atkins and suspended winger Tom Lineham.
