Two defensive errors proved costly for Lincoln City as they crashed to defeat against promotion hopefuls Luton Town at Sincil Bank.
The Imps nearly broke the deadlock midway through the first half when Mark Tyler saved brilliantly from Adam Smith.
But Paul Farman fumbled Andre Gray's cross over the line in the 28th minute to gift Luton the lead.
Jon Shaw was then left totally unmarked to put Luton further ahead just after the break.
But a stunning effort from Jamie Taylor reduced the deficit to give Lincoln hope of a draw.
However, they could not find a way through as Luton maintained the pressure on the leading pack at the summit of the Blue Square Bet Premier.
