The Pilgrims led for two thirds of the contest at Gander Green Lane against Sutton United, with Carson's 32nd minute free-kick handing Graham Coughlan's side the lead.

They held that advantage until the fourth minute of stoppage time when Ogbonna's cross looped up off Jordy Hiwula to deceive Rhys Lovett, who subsequently denied Jack Taylor with a stunning save at the death.

Chances were at a premium early on, with United fielding an unchanged starting XI following Wednesday's victory over Braintree Town.

The Pilgrims took the lead when CARSON lined up a 20-yard free-kick and arrowed the ball beyond a static Jack Sims.

Sutton responded with Jayden Harris blasting goalwards - with Lovett making a flying save to his right. Noa Boutin's left-wing cross was subsequently headed against the post by Brandon Njoku.

United introduced Alex Lankshear and Jordy Hiwula 10 minutes in the second half and it was the latter who sent a header over the bar after meeting Kieren Donnelly's cross from the right.

As the match ticked into seven minutes of added time, the Pilgrims had a glorious chance to kill off the contest but Dylan Hill was only able to fire off target after rounding a wandering Sims outside his box.

Sutton levelled when OGBONNA saw his cross from the right loop up off Hiwula and spin high over the head of Lovett.

Boston's number one preserved a point in the last act of the game with a stunning low save to his left to deny Taylor.
