Upwell sailed into the quarter-finals of the North Cambs Cup with a 5-3 win over Cambs Division Two side, March Rangers.
Upwell fell behind for the first time this season after a stunning volley from 30 yards.
However, Jack Watson equalised soon after and in-form Aaron Marshall netted two minutes later.
Watson scored his second of the game to put Upwell 3-1 up at half-time.
Within 10 seconds of the restart Jonny Allen scored what he described as his best-ever goal, running onto a ball played forward from the centre kick, nipping past a March Rangers midfielder and launching an unstoppable shot into the top right hand corner of the visitors’ goal.
Rangers replied twice, but Allen put the result beyond any doubt.
