Rhinos sit in third, joint on points with Warrington and just three points away from the Giants, despite having played three games less than all of their top half rivals.
Saints head into the clash with Leeds in ninth and are on a run of five straight defeats, their longest losing run since 1994.
Carl Ablett and Jamie Peacock both face spells on the sidelines for Leeds after picking up injuries in the cup exit. Centre Ablett and prop Peackock are both expected to be out for eight weeks, while teenager Liam Sutcliffe could make his debut at Headlingley Carnegie.
Jon Wilkin returns from a two-game suspension to boost Nathan Brown’s underperforming Saints while Ade Gardner has completed a similar ban and is available for selection. Jonny Lomax and James Roby are both a few weeks away from full fitness yet and Francis Meli is ineligible as a depleted St Helens travel across the Pennines.
Leeds Rhinos 19-man squad: Hardaker, Watkins, Moon, Hall, McGuire, Burrow, Leuluai, McShane, Jones-Buchanan, Sinfield, Delaney, Bailey, Kirke, Clarkson, Achurch, Moore, Singleton, Vickery, Sutcliffe.
St Helens 19-man squad: Wellens, Gardner, Turner, Soliola, Hohaia, Perry, McCarthy-Scarsbrook, Puletua, Wilkin, Manu, Laffranchi, Jones, Makinson, Ashe, Greenwood, Walmsley, Percival, Thompson, Howarth.
Prediction: Leeds to pile more misery on St Helens‘ season – home win.
