Anthony Scully’s 10th goal of the season helped the Imps to an impressive battling victory at Burton Albion.
Scully’s strike proved decisive after Lewis Fiorini’s fourth goal in three games had given the visitors an early advantage.
A frenetic finish saw the Imps twice go close to extending their lead, although in the end it needed a fantastic flying save from Josh Griffiths in the sixth minute of time added on to preserve the lead after Conor Shaughnessy had pulled one back for the Brewers.
