Hornets’ coach John Stankevitch said: “While we want to win the game this week, it’s about building momentum for the following week and I’m not going to take any unnecessary risks. If players aren’t 100 per cent, they probably won’t play.”
Jamie Peasnell is also out for four months after suffering a medial ligament injury just eight minutes into last week’s 50-10 defeat at Widnes.
Stankevitch added: “I’m not sure what Doncaster will be like. Last year they started the season poorly, but they got really strong towards the back end of the season. I’m not too sure what to expect on Sunday.”
Dons’ coach Tony Miller was proud of his side’s effort last week.
Dewsbury eventually emerged 30-18 winners at the Keepmoat Stadium, but Miller said: “Dewsbury are a division above us and you couldn’t tell.”
Miller is set to make a number of changes for the trip to Lancashire. He said: “Now we can’t progress in the Northern Rail Cup, we will give everybody the opportunity to prove themselves.”
