Doncaster coach Tony Miller remains hopeful, despite watching his team fall to a 40-20 defeat against Blackpool in their midweek Northern Rail Cup clash.
Miller said: “We’re heading in the right direction and I’m sure that we’ll give a good account of ourselves against York on Sunday.”
Paul Stamp is struggling to be fit for York after suffering a back injury against South Wales Scorpions last week, but loan signing John Davies could feature after linking up with the Knights from Castleford Tigers.
York’s assistant coach Chris Thorman said: “It was important for us to get back to winning ways.
“We’re not hitting our straps by any means, but if we improve again this week then we’ll be happy.
“It’s important that we know we can win ugly when we need to do.
“We’ve done it against Leigh and South Wales and having that knowledge that we can do that, particularly in close, high pressure situations, will stand us in good stead.”
