Doncaster Toll Bar retained top spot in the Pennine Amateur Rugby League Premier Division despite suffering their first defeat.
The home side flattered to deceive when going down 38-14 against Castleford-based Fryston Warriors.
Former Dons captain Craig Lawton capped a man-of-the-match performance with a try, with Steve Mills and Kieran Cross also touching down.
Shaun Roberts could only add one conversion on the day as last season’s Championship winners suffered a rare home defeat.
“We are really disappointed with the way we played overall,” said Toll Bar coach Ian Tattersall.
“We were the better side for most of the first half but we were really poor in the second.
“We made way too many errors and asked too much of ourselves defensively. At this level we just can’t afford to play like that (and expect to win) but we will learn from the experience and be better for it.”
Local rivals Moorends Thorne Marauders are still looking to get off the mark after going down 28-20 at Sherburn Bears.
n The Toll Bar club will host a star-studded touch and pass game as part of Shaun Leaf’s testimonial on Saturday.
The game, which kicks-off at noon, will include a number of Leaf’s former Doncaster RLFC team-mates including ex-player-coach Paul Cooke.
Entry to the game, and the various other attractions, is £10.
The longest-serving player on the club’s books at the time, Leaf retired on medical advice midway through last season.
