Doncaster's hopes of avoiding relegation from the Championship have been boosted by the return to the fold of record try-scorer Lee Waterman this week.
Having played a leading role in helping to secure the Dons promotion in 2012, when he bagged over 30 tries, Waterman has more incentive than most to keep the club in the Championship.
Speaking ahead of tomorrow's crucial four-pointer against the Cumbrians at Castle Park (3pm), Waterman told the Star: "I still think we can stay up. If we can beat Whitehaven and then go on a winning streak who knows what can happen?"
Second-rower Steve Snitch and dual-registered Hull FC second-rower Jansin Turgot are both available after missing last Friday’s defeat at Featherstone.
Half-backs Richard Wilkinson and Paul Mennell and props Mitch Clarke and Russ Spiers have all recovered from knocks against Rovers.
Looking ahead to the game, Thornton warned: “I’ve seen footage of several of their recent games, two of which they’ve won, and they are a good team.
“So we know it’s going to be tough but I’m hoping that the intensity of our last three games, all against top sides, will work in our favour.
“We’ve matched Bradford, London and Featherstone, but not for long enough periods and I’m hoping that we can play at play at that level for longer periods tomorrow and give ourselves a chance.
“I think the first 20 minutes will be crucial and I’m hoping that we can take the game to them and turn pressure into points.
“What I want us to do is get in front and then build on it and try and get ourselves two or three scores in front and then we can start playing with a bit of composure.”
