Nelson went down to a 2-0 defeat against Cammell Laird 1907 at Kirklands on Saturday, in their first game since the 3-0 win at Bacup Borough on Boxing Day.
The Admirals had taken four of their nine-point tally in their previous two games.
And, in total, they were three games without defeat – including the Macron Cup win on penalties at Prestwich Heys – with real signs of improvement under Steve Cunningham.
But goals in each half saw the Blues beaten in Birkenhead.
Mark Bainbridge gave the hosts the lead after 17 minutes, a lead they held until the interval, as a deep free kick from Jay Thomas was floated in, Josh Maldon cushioned a header across goal and the home captain provided a terrific first time finish for his first goal for Cammell Laird.
After the break, Adam Rooney had the ball in the net for Lairds after a deflected free kick, but the flag went up for an infringement.
That didn’t matter just before the hour as Tom Murray sent Ben Holmes clear with a brilliant 60-yard pass, and Holmes made it 2-0 with a cool finish past Marcel Wusiewicz.
The game finished late as the floodlights went off for a spell, with a short delay before the game resumed, but Nelson couldn’t retrieve the situation.
Nelson will look to get back on track when they host AFC Blackpool tomorrow, and have no midweek game before Daisy Hill visit Victoria Park on Saturday, January 20th.
Meanwhile, talented Burnley youth goalkeeper Wusiewicz has extended his loan with the Admirals until the end of the season.
