Portsmouth extended their unbeaten run to five matches after a goalless draw at home to Stevenage.
The visitors had the ball in the net after half an hour, but Filipe Morais' effort was ruled out for offside.
Morais was also close to breaking the deadlock after the break when his flicked header bounced just wide.
Home sub Adam Webster saw his diving header caught by Boro keeper Steve Arnold before Marcus Haber nodded against the Pompey crossbar late on.
Portsmouth are now two points behind Oldham, who occupy the position immediately above the relegation zone, but the Latics have three games in hand on the Fratton Park outfit.
VIEW FROM THE DRESSING ROOM
Portsmouth caretaker manager Guy Whittingham told BBC Radio Solent:
"It's pleasing that we haven't conceded again at Fratton Park, that's the most important thing, and probably encouraging towards the end where we've got four under-19s on there and we look like the team that's going to score.
"Ultimately it's a point gained because we gained on the two above us. It's disappointing because you want to win every game but we'll take encouragement from the performance.
"I'll probably argue we should have won and they'll probably argue they could have won at the end when they hit the bar but it's all about the performance for me.
"We didn't look as sharp as we had done in the past, we didn't play the ball on the floor as much as we could have done, didn't play enough football but we defended resolutely again and that's so important."
On the upcoming court case: "I think like everybody we just want to know the result. We can't affect that, all we can affect is the stuff on the pitch and hopefully things off the pitch will work for us and that's all we're hoping for."
Stevenage manager Graham Westley told BBC Three Counties Radio:
"It's a second clean sheet in a week, it was a hard earned clean sheet. I thought the players showed good organisation and good resilience.
"We could easily have scored two or three goals today from pretty clear cut chances and we didn't give many away."
