Match ends, Mansfield Town 0, Oldham Athletic 0.
Oldham defender Cameron Dummigan was the hero as his two goal-line clearances prevented Mansfield from upsetting their League One opponents.
League Two Mansfield had the better of the match, with Reggie Lambe also putting a volley over from five yards.
Dummigan cleared shots from Matt Green and Nathan Thomas as the Stags dominated the second half.
But Mansfield could not record a second win in seven FA Cup meetings against Oldham.
Oldham Athletic manager David Dunn told BBC Radio Manchester:
"As you saw with Salford and Notts County, there are many banana skins out there. We made sure we were solid and didn't cave in. The commitment and enthusiasm that the lads played with out of possession was good. In possession we need to do a lot better than that.
"A clean sheet is always good, you can build a lot on clean sheets, that's where the wins come from. I'm not going to lie and say I was really pleased with anything.
"Some of the lads weren't on song today. We looked laboured at times in possession but we kept going. We huffed and puffed."
