Huntingdon suffered last-gasp agony as they were condemned to defeat by a final-minute try yesterday.
Stags suffered a fourth successive reverse in Midlands Division One East as they went down 22-21 at Wellingborough.
Damien Whales’ men had earlier led thanks to tries from Dan Malem and Billy Bates.
Malem also kicked three penalties and a conversion before being one of three Stags players to go off injured – Nick Vallance and Wayne Bradley were the others.
St Ives remain bottom of Midlands Division Three East (South) after being beaten in a basement battle at Rugby St Andrew.
The depleted Bulls delivered a battling display as they went down 20-6.
Luke Slade kicked them into the lead with a penalty, but a converted try and a penalty put the hosts in the driving seat before the break.
Slade successfully guided over another penalty to keep St Ives in contention before a loss of possession gifted St Andrew a try in the corner.
Then, as tiredness set in late on, St Ives conceded another try.
St Neots were beaten 46-21 at unbeaten table-toppers Oundle in the same division.
