Grimsby missed the chance to move to the top of the National League table as Bromley came from behind to claim a 3-1 victory.
John McAtee’s clever free-kick gave the previously unbeaten visitors the lead in the 43rd minute but Michael Cheek cancelled that out from long range 12 minutes after half-time for his seventh of the season.
Bromley took the lead in the 67th minute when former Grimsby loanee James Alabi found the net from a tight angle, and the Mariners suffered another blow two minutes later as Michee Efete saw red for a foul.
The hosts made sure of the points nine minutes from time thanks to Corey Whitely’s long-range effort.
