Leeds have included centres Kallum Watkins and Carl Ablett in their Challenge Cup final squad, as they look to prove their fitness.
Watkins will have a late fitness test ahead of the Wembley showdown with Wigan Warriors and is currently rated 50-50 with a knee injury, even though he was originally expected to miss the showpiece event.
Meanwhile, the experienced Ablett looks more likely to feature, with the 25-year-old winning his race to recover from an ankle injury sustained in the defeat to Harlequins last weekend.
Pre-match favourites Wigan have included fit-again Lee Mossop, Andy Coley and Brett Finch in their squad after the trio were rested against Bradford last week.
Prop Eamon O'Carroll drops out of the 19-man party, while Paul Prescott is expected to replace Ben Cross at prop, with the later sidelined with a broken arm.
