Gillingham scored a controversial injury-time penalty to snatch a 1-1 draw at relegation-threatened Oldham.Duckens Nazon put the Latics on course for a crucial win but there was late drama as they had Wilfried Moimbe sent off before Tom Eaves levelled from the spot.Visiting goalkeeper Tomas Holy made two fine saves in the first half, rushing off his line to deny Nazon and somehow blocking George Edmundson's header.At the other end, Gillingham went close to a breakthrough when Conor Wilkinson forced Johny Placide to beat away his angled shot.Oldham took the lead moments before half-time as Jack Byrne found Nazon, who battled his way into the penalty area and drove inside the far post from 12 yards.Wilkinson was inches away from a Gills equaliser before, on the hour, Placide did superbly to grab Jake Hessenthaler's goalbound header.Oldham wasted chances to double the lead and they were punished in the 90th minute when referee Michael Salisbury pointed to the spot after an off-the-ball incident involving Moimbe.The defender received a straight red card and Eaves drilled home the resulting penalty.
