The Union will look to clinch the second Major League Soccer playoff berth in the franchise's seven-year history when they host Orlando City 3 p.m. Sunday at Talen Energy Stadium.
A win in either of their final two regular-season games would earn the Union one of the six Eastern Conference playoff spots.
The top two teams in the conference will earn a bye and the remaining four will play a single-elimination, first-round game. The Union can't earn a first-round bye and the highest they can finish is fourth place.
In case of a tie, the first tiebreaker will be total wins.
