League One leaders Doncaster Rovers could only muster a draw at home to struggling Portsmouth.
In a scrappy first half, Chris Brown stabbed home his 10th goal this season from David Cotterill's low cross at the near post to give Rovers the lead.
Defender Rob Jones had a fine opportunity to double the advantage, but volleyed over from six yards out.
Pompey made them pay when Jed Wallace finished from close-in with his side's first real chance to level matters.
Wallace almost followed up his strike with a second, but his effort crept just wide of the post as neither side could find a winner.
The point means Portsmouth lie seven points away from safety, while Doncaster, who failed to capitalise on Sheffield United's heavy defeat at Stevenage, are two points clear of second-placed Brentford.
VIEW FROM THE DRESSING ROOM
Doncaster Rovers manager Brian Flynn told BBC Radio Sheffield:
"I think it's a point gained, because I don't think we were at our best today.
"We weren't good going forward and that's part of our strengths.
"We have got a strong defensive unit, we know that. But I don't think our service to our two main strikers was good today."
Portsmouth caretaker manager Guy Whittingham told BBC Radio Solent:
"I think it's a tremendous point, especially really after the disappointment of Tuesday [a 1-0 defeat at Leyton Orient] where we've played so well and come away with nothing.
"I think to come up here and come from 1-0 down to come away with a draw at the league leaders I think is a fantastic effort.
"It's been building. I think if you take the results out of it, the performances have been really encouraging for the rest of the season and for next season."
"I don't think it's any coincidence that the group of players we've got together have worked hard together on the training pitch, have worked hard on the football pitch and have got to know each other a lot better and the football's better too."
