King’s Lynn’s hopes of avoiding relegation from the National League suffered a huge blow after Paul McCallum’s stoppage-time strike rescued Dagenham a 1-1 draw.

The cruel equaliser left the Linnets seven points from safety with three games remaining, with the Daggers four points off the play-off spots.

Josh Coulson put King’s Lynn in the lead after 12 minutes, heading past Elliot Justham from a corner.

The Daggers had chances, with Junior Morias and Matt Robinson going close before Sam Ling’s shot flew wide just before half-time.

Dagenham thought they had found the equaliser in the 87th minute but Josh Walker’s goal was ruled out only for McCallum to strike in stoppage time, slotting past Paul Jones to rescue a point.
