Lincoln earned a point in their first game since manager Keith Alexander was put "on leave" thanks to a goalless draw at Mansfield. Mansfield started well and should have taken the lead on 18 minutes but Adam Rundle's shot was cleared off the line.
Stephen Dawson and Jonathan D'Laryea missed superb chances as Mansfield took the game to Lincoln after the break.
But Lincoln were denied by keeper Kevin Pressman while Simon Yeo hit the post with the rebound.
