It could have been even better for Graham Coughlan's side, who played against 10 men from the 41st minute following Danny Collinge's rash challenge on Oisin Gallagher, which saw the Lincoln City loanee substituted due to damage to his right ankle.

Chances were at a premium throughout - but the point could prove valuable in the Pilgrims' survival quest, while Barnet extended their unbeaten run to 16 games in the process.

The game's first meaningful opportunity fell to the Pilgrims in the 28th minute when Jai Rowe headed narrowly over the bar following Keaton Ward's corner delivery.

United lost the services of Gallagher before the break - with Barnet's Collinge overrunning the ball and subsequently crunching the on-loan Imp.

The hosts struck the crossbar in added time at the end of the half, with Connor Teale seeing his flick deflected on to the woodwork and behind for a corner.

Tony Weston crashed a drive off target after the break, while Cameron Gregory made a crucial grab to deny Callum Stead at the mid-point of the half.

The Pilgrims launched a late bombardment, but Barnet defended manfully to preserve their clean sheet - and proud unbeaten record.
