A blistering second half sealed victory for Percy Park Lions as they scored 36 unanswered points to inflict the first league defeat of the season against leaders Darlington Mowden Park II.
Park were down in the first three minutes when Mowden scored a converted try before the visitors scored a second try ten minutes later after charging down a clearance kick.
When Percy Park conceded another converted try to fall 21-0 behind points things looked bleak.
On 28 minutes an inspirational solo try by skipper Jonny Dubois gave his side hope.
Mowden responded almost immediately with another converted try and with time ebbing away in the first half, Park were awarded a scrummage in the Darlington half.
A No.8 pick up by Jack Davison and a pass to scrum half Stevie Irving set play away down the left hand flank and Oscar Pritchard received the try scoring pass to go over the line for an unconverted try.
Park were down 12-28 at half time and the supporters could have no perception as to how the tide would turn and Mowden capitulate so spectacularly.
With just seven minutes gone in the second half Phil Morse broke through the defensive midfield to score under the posts. A further two tries, the second from Oscar Pritchard, gave Park a single point lead 29-28 on 66 minutes.
Mowden who had travelled with a squad of 17 seemed to be dropping like flies, with both replacements used, they were down to 14 as a further player limped off and at the end were down to 13.
Tries on 70 minutes by Olly Walker then Zak Rutter and finally Leo Caulfield on 80 minutes gave Park a convincing 48-28 win, for stand in coach Chris McDine.
Meanwhile, Percy Park first XV’s disappointment at going down to a last minute try at Morley was understandable as the side led 29-17 with only ten minutes remaining.
It looked as though Park were set to record a bonus point away win having scored four tries through Olly Walker, Jimmy Baldwin, Stu Cannon and a penalty try.
But they collapsed in the final ten minutes and conceded three tries to lose 32-29 in the SSE National 3 North.
Next week the coaches will be looking for a return to form as they meet Penrith at Preston Avenue.
