Bedlington are still seeking their first win of the season after Celtic Nation picked up their first three points at the Terriers’ expense.
Bedlington made the worst possible start as they went a goal down just two minutes into the contest.
A long ball by Ian Douglas alluded the back four and fell to Michael Reed, who found himself one-on-one with advancing goalkeeper Sean McCafferty and he kept his composure to calmly slot the ball into the bottom corner.
The remainder of the first half saw both goalkeepers untested aside from a long-range set-piece effort from Bedlington which was comfortably tipped over the bar as both sides struggled to get going.
Terriers’ manager Ian Skinner rang the changes at half-time with youngster Keelan Nellis coming on at centre back for Joe Kendrick and Steven Scott replacing Sam Walton in midfield.
Bedlington were a lot livelier in the second half and looked the most likely to score with Jordan Nellis just shooting wide after being put through behind the defence.
Bedlington also had a penalty appeal turned down after Nellis was bundled over in the box by a Celtic defender.
In a game with few clear-cut opportunities, the best chance of the half fell to Bedlington striker Connor Winter as he was cleverly played in by Nellis, but his low powerful drive flashed past the post.
The Terriers were punished for their wastefulness as Celtic doubled their advantage against the run of play from a corner with centre back Tyran Taylor heading home from close-range.
Celtic endured a nervy last 15 minutes as goalkeeper Adam Toward was sent off for a deliberate handball.
But their defence remained resolute as they held on for the victory.
Skinner said: “We gave away two very poor goals and although we enjoyed long periods of possession we never really threatened the goal, which was disappointing.
“Our performances have been OK in the opening games but we need to improve in the final third.”
Terriers drew their opening fixture 0-0 before losing in midweek 2-1 at home to Whitley Bay.
