Huddersfield secured promotion back to National Two North at the first attempt with a 38-19 victory at home to Percy Park.
They overhauled Stockport to capture the title, simultaneously consigning the visitors to relegation.
Park scored an early try but Huddersfield responded positively. Winger Elliott Hodgson got his side back in the game with a typical burst of pace and captain Nick Sharp used all his experience to go over.
Hodgson scored again minutes later, leaving men trailing in his wake, and the third successful conversion from full-back Tom Hodson made it 21-5.
Park were gifted a route back into the game with two quick tries, one of them converted, to leave only two points in it at the break.
A long period of tense rugby was broken when winger Dave Hall, playing his first game of a season ravaged by injury, scored and Hodgson converted. Scrum-half Joel Hinchliffe’s interception try from halfway confirmed the outcome before a late penalty completed the scoring.
A final remaining home game with Sandal provides the opportunity for a celebratory send-off for first-team manager Lee Paxman, who will depart the club this summer after 10 years’ loyal service.
A combination of injuries and Easter unavailabilities led to Harrogate taking a weakened side to Birmingham Solihull for a rearranged National Two North fixture but they produced a top-class display and won 33-24.
The hosts raced into an early 12-0 lead but tries from Aarin Yorke, Phil Wickham and Luke Edwards put Harrogate on top.
James Audsley-Beck scored after the interval but the hosts hit back to within four points before Edwards scored the game’s final try.
Relegated Sheffield Tigers were put to the sword 69-5 by promotion-chasing Darlington Mowden Park at Dore Moor.
The North-East outfit moved up to second spot and look set for a play-off battle in their bid to reach National One.
Left winger Shaun McCartney’s early try was converted by Tom Hodgson for the visitors, and although Tigers hit back with hooker Tom Coates scoring after 15 minutes, that was to be as close as they would come to leading.
Mowden Park led 24-5 at the break with further tries from Chris Peace, Zylon McGaffin and Ollie Hodgson and Hodgson went on to score twice more as Darlington went on the rampage.
Tigers lost four key players to injury as Cameron Mitchell and flanker Will Macauley also put their names on the scoresheet, along with a penalty try.
