The Union are in desperate need of three points after managing to collect just one win in 10 games so far this season.
Despite an offseason roster overhaul, it's been a rough start for the Philadelphia Union.
John Hackworth's team added Cristian Maidana, Vincent Nogueira and Maurice Edu to the midfield in the offseason, as well as Austin Berry to the defense. Those additions have only resulted in a 1-4-5 record thus far, with a frustrating 2-1 loss at Seattle on Saturday the latest tough result.
D.C. United has already equaled its win total from 2013 with three, but the Black-and-Red dropped a 3-2 result at Portland on Saturday, with Max Urruti scoring a winner at the death.
Sean Franklin and Eddie Johnson missed that match because of injury. Franklin will likely miss the game at PPL Park, while Johnson could return for what may be his last United game for a while, as he is set to be called into Jurgen Klinsmann's pre-World Cup camp. Edu, on the roster bubble as well, is likely to join EJ in northern California next week.
