Having faced the league’s top three in successive fixtures, there looked to be some respite for the Zebras against Immingham Town who sat a place lower in the table, but Brigg were sunk 5-3.
The visitors trailed 3-1 at the break despite Ben Lingard’s penalty after 19 minutes, with Daniel Simpson netting a first-half hat-trick for Immingham.
Paul Ashton pulled one back just three minutes into the second half, but a fourth goal from Simpson and another from Gary Nimmo sealed the three points for the home side before Tom Wilson scored a last-minute consolation.
The result dropped Brigg a place to 10th, but they are still within four points of Cleethorpes in sixth.
The Zebras now have two weekends off before returning on Saturday, Febrary 8 at home to Horncastle Town.
