Lincoln clinched a place in the play-offs for the fourth season in a row with a draw with Rochdale.
Lincoln took the lead in the 72nd minute when a corner from Scott Kerr was headed home at the far post by Gareth McAuley.
Nat Brown then smashed a shot narrowly wide but Rochdale were rewarded with an equaliser two minutes from time.
Ricky Lambert swung in a free-kick from the left which flew into the net with keeper Allan Marriott stranded.
