Grimsby hit back with two late goals to secure a point against Newport in the Blue Square Bet Premier.
Wayne Hatswell's header gave Newport the lead in the opening minute before Nat Jarvis extended their lead.
Grimsby barely troubled keeper Danny Potter until the 79th minute when Serge Makofo pulled a goal back.
And they equalised with three minutes remaining with Anthony Elding scoring from the penalty spot after a Andrew Hughes handball.
VIEWS FROM THE DRESSING ROOM
Grimsby Town joint-manager Rob Scott tells BBC Radio Humberside:
"After the first few minutes or so, we were all over the show.
"But you have to pick positives because I know what everyone else is going to say - we're positive that we came away with a point rather than none.
"They scored two goals in the first half and that puts you on the back foot. Everything then becomes harder, for the players, the fans, and rightly so. It takes big characters to get on the ball when things aren't going your way."
Newport County manager Justin Edinburgh told BBC Radio Wales:
"It's quite clear it wasn't a penalty. I think the referee's got it wrong. It's no doubt he's cost us the three points here today.
"It was a fantastic away performance and unfortunately it's been undone by someone's poor misjudgement.
"I think we controlled the game. Their first goal gave them a lift and then obviously we've had the points taken away by a very poor decision by the referee."
