The Union could have strengthened their playoff position, but a late goal from Montreal left them with another tie that likely felt like a loss.
Matteo Manosu's bouncing header at the far post in the 88th minute was the equalizer as the Impact played the Union to a 1-1 draw on Saturday night at Talen Energy Stadium.
The Union, who began the day in fourth place in the Eastern Conference, are 11-10-8 for 41 points. Montreal, right behind the Union, is now 9-8-11 for 38 points. The top six teams in the conference will make the playoffs.
