BOSTON United boss Jason Lee was left rueing his side’s disallowed goal following Saturday’s goalless draw with Nuneaton Town.
A spirited Pilgrims side put in a good performance again the promotion-chasing Borough, and thought they had snatched victory with three minutes to go.
Leon Constantine tapped in from close range after Danny Alcock could only parry Danny Sleath’s strike.
But as Boston celebrated, an offside flag denied the substitute his second goal for the club.
“At the end we could have snatched it. But the linesman - with his great decision - decided he was offside,” said Lee with more than a hint of sarcasm.
“Before that I was very pleased. The message was to keep a clean sheet and the boys performed.
“You expect the away team to have a few opportunities but, from my point of view, I thought the result and performance were positive.”
Defender Conor Marshall made his debut and helped the Pilgrims to their fifth clean sheet of the Blue Square Bet North campaign.
He said: ““I thought it went well today.
“It was a good debut, as far as I’m concerned.
“The team did well and we kept a clean sheet, which is always good as a defender.
“We’ve been on about it all week in training – keeping a clean sheet.
“The managers have been going on at us and on at us about it, and that’s what we’ve done with a good performance
“We were the better team and deserved the win.”
