MK Dons defender Dean Lewington played his 916th game of his career
Grimsby slipped out of the League Two play-off positions after a goalless draw at MK Dons.
With Salford beating Colchester, a draw saw the Mariners fall out of the top seven on goal difference ahead of next weekend's season finale after they failed to leave Stadium MK with three points.
MK Dons were using their final home game of the season to celebrate club captain Dean Lewington, who announced his retirement from playing earlier this month and made his first appearance since November before being substituted in the 69th minute.
"I'm not always one to show emotions but it got to me a little bit today," Lewington told BBC Three Counties Radio.
"I've not played 90 minutes all season and there was no way I was going to last that long. I could feel my legs getting a bit tired and I didn't want to be at fault for a goal or cost the team.
"It's amazing, the 20 years have flown by. It's been so long but it feels so short."
The Dons had a decent chance when Connor Lemonheigh-Evans' shot was well denied by Grimsby goalkeeper Jake Eastwood.
Grimsby thought they had scored when Danny Rose touched in Denver Hume's cross, but an offside flag interrupted his celebrations.
Rose had another effort disallowed just after half-time for a foul on Dons goalkeeper Craig MacGillivray, before Eastwood made saves to deny Lemonheigh-Evans and Scott Hogan.
Grimsby's Kieran Green saw a free-kick strike a post late on, while the visitors' Evan Khouri and the Dons' Laurence Maguire both missed chances for a stoppage-time winner.
