The Philadelphia Union are without starting defenders Danny Califf (center back) and Jordan Harvey (left back) tonight, and Peter Nowak's starting line up clearly shows those loses.
Harvey was lost for tonight's game against the Portland Timbers because of a red card that he received during the Union's game, last week, against the San Jose Earthquakes. Califf was ruled out by the team because of an undisclosed illness.
The Union's Farfan twins, Michael and Gabriel, will both start along the back four, becoming the first set of twins to ever start a game in MLS play.
