at-trick of victories over London Broncos on Monday as they bid to cement a place in the Kingstone Press Championship Shield’s top two.
The Rams recorded a notable 20-16 win at The Hive in April and completed the double over the full-time opponents with a 24-12 success at home.
A third-straight victory over London would see the Rams move five points clear of the Broncos and on the verge of guaranteeing a home semi-final in the Shield.
Coach Glenn Morrison said: “We beat London in a friendly and then did the double over them, so we know if we play well we are capable of beating them.
“This game will be the big factor in who finishes second and gets a home semi-final.
“Our aim at the start of the year was the top two, to get a home semi-final and give ourselves the best chance of reaching the Shield Grand Final.”
Dewsbury slipped to a 42-30 defeat at home to Whitehaven last Sunday but Morrison is confident his side will produce a better display against London.
He added: “Whitehaven are in good form, they put 40 points past London, 30 past Featherstone and did the same to us.
“They are a good side who are pushing for the top four but we know we can perform better than that.”
Aaron Brown suffered a shoulder injury against Haven, while Makali Aizue and Luke Adamson also picked up knocks, although on-loan back Etu Uaisele should be available to return against London.
Scrum-half Anthony Thackeray needs three tries to reach 150 in his career, which includes 39 for Dewsbury, while Shane Grady is the leading try scorer in the Championship Shield with five following his brace last week.
