Playoff chase resumes with D.C. and Chicago in action Wednesday night

Time is running short for D.C. United and the Chicago Fire, and an accelerated level of stress is put on each of the remaining regular season games for two teams with postseason aspirations.

As two of the three teams on the outside of the current playoff picture but within striking range, United and the Fire need to pile on the results beginning with tonight's matches against the Vancouver Whitecaps and FC Dallas, respectively.
