Luctonians director of rugby Alex Davidson says his side must beat Harrogate to maintain their National Two North play-off challenge.
Lucs could secure a double this season after winning the home fixture 38-12.
"It was the first game where the backs really looked dangerous and Will Burton scored two tries and showed his class," he told BBC Hereford & Worcester.
"That was the major difference on the day so we will be looking to do the same again up there."
After winning three successive matches in the run up to Christmas, Luctonians have since been beaten 14-0 at Westoe, in their first game of 2012, and last weekend's scheduled home match against Sheffield Tigers was postponed.
While Davidson knows Saturday's game will be difficult, he believes Harrogate are going through a transitional phase.
"I think they have been suffering and certainly I believe they have lost quite a few players from last season," he said.
"They had a link with Leeds academy earlier in the year and that is faltering slightly in terms of the quality of player they are receiving.
"But obviously any team in this league is dangerous and we'll go at it 100%."
Luctonians recently brought in the former Worcester Warriors scrum-half Louis Silver on loan from Bristol but he will have to make do with a place on the replacements' bench at Harrogate.
Davidson says he plans to start the game with the side that was due to take to the field against Sheffield Tigers.
"We're going to leave the squad exactly the same as it's only fair, really, given you have told boys they are going to be playing," he said.
"It would take some explaining to tell them how in the space of a week in which there has been no game they can be dropped.
"We'll bring boys on so Louis will sit on the bench and hopefully get a run at some stage."
Coverage of Luctonians match at Harrogate on Saturday, 21 January is on BBC Hereford and Worcester from 1400 GMT.
