Adam Bowman is unlikely to feature for Rochdale after suffering a fit.
Hornets coach John Stankevitch said: “It’s a big blow for us, because we weren’t particularly blessed in terms of numbers in the outside backs anyway.”
Stand-in York coach Chris Thorman says his focus is centred on York’s performance rather than anything Rochdale can do.
Thorman said: “It’s the first competitive hit out for everyone this weekend and, like ourselves, Rochdale will want to set the standard for the rest of their season.
“It’s a bit of an unknown for me, going into a competition against a lot of teams that I don’t know, but the boys have been tremendous in training.
“All I’m concerned about is the contribution from the York players and the effort and commitment they show on Sunday.”
