The sides both picked up a long-term injury during a Betfred Challenge Cup defeat last weekend. Wigan also have a doubt over full-back Jai Field, but he has been named in their initial squad along with winger Abbas Miski following a two-game layoff.
Scrum-half Matt Frawley is back in contention for Leeds after concussion and prop Tom Holroyd is available following a two-match suspension, but two of their top-20 squad numbers remain on the casualty list, alongside several fringe players. Here’s who is definitely ruled out and when they could be back on the field.
