Union-Fire Preview (The Associated Press)

After back-to-back victories lifted them into a tie atop the Eastern Conference, the Philadelphia Union have been eager to get back to work following a two-week layoff. Now they could be catching a break if Chicago Fire star David Accam remains sidelined. As coaches Jim Curtin and Veljko Paunovic face clubs they played for Saturday night, the visiting Union chase their third straight victory and first against winless Chicago in nearly three years.
